An exhaust does more than make noise — it open up the engine’s true breathing potential. The right one reshapes throttle response, sheds weight from the rear end, and delivers a note that changes the whole personality of your ride. The problem is that slip-ons, full systems, and universal pipes don’t interchange, and a mismatch wastes your time and cash.
I’m Min Islam — the founder and writer behind Trending Car. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you are hunting a deep rumble for a bagger or a screaming top-end for a sportbike, these nine picks cover the real range of what the exhaust for bikes market actually delivers, with the specs and fitment quirks that separate a weekend project from a headache.
Our Picks at a Glance
How To Choose The Best Exhaust for Bikes
An exhaust swap can be the single most satisfying upgrade you make, but the wrong one turns into a lean-running mess or a fitment fight. Focus on these three factors to narrow the list.
Slip-On vs. Full System
A slip-on replaces only the muffler can, which is a quick bolt-on that changes the sound and drops a few pounds. A full system replaces the header pipes and the muffler, which gives a bigger power gain but often requires a fuel tuner or a jet kit so the engine does not run too lean (an air-fuel ratio that runs too hot). For most riders, a slip-on is a safer, cheaper starting point.
Connection Diameter
The connection diameter — the size of the pipe where the muffler meets the header — must match your bike’s stock pipe. A 38mm inlet is common on many dual-sport and pit-bike exhausts, while a 2.5-inch or 4-inch opening appears on Harley touring models. Buying a 35mm system when your bike uses a 38mm pipe guarantees a bad seal and a loud leak.
Baffle vs. Open Pipe
A baffle is a perforated tube inside the muffler that reduces volume and shapes the tone. Some exhausts ship with a removable baffle, so you can choose between street-legal noise and full straight-pipe volume. The “super loud” versions ship with no baffle at all, which sounds aggressive at idle but can become fatiguing on a long highway ride.

In‑Depth Reviews
1. 11-16 Suzuki GSXR600 & 750: M4 GP Series Slip-On Exhaust – Black
Our pick — over 4.5★ from 350+ verified ratings; the strongest balance of quality and price.
The slip-on that gives a GSX-R a healthy bark without requiring a remap.
You get that deeper, more aggressive note at low RPMs, and it turns into a proper scream when you rev it out. Buyers report an easy 15-minute install using a metric Allen wrench and a socket wrench — the only real trick is reusing the rubber grommet.
Unlike the heavier full-systems on this list, the SU6112-GP saves significant weight off the rear and does not force you to rejet the bike unless you also remove the catalytic converter. The black finish matches the stock look, and the included baffle keeps the volume street-friendly while still being noticeably louder than stock.
The catch is that the heat shield is not included, so you will want to reuse the stock one or order an aftermarket piece if you ride two-up. At a 380-review average of 4.7 out of 5, this is the most polished slip-on option here for a GSX-R owner.
Why it wins
- Deep growl at low RPM, full scream at high RPM
- No remap needed unless cat is removed
- Easy 15-minute bolt-on install
One detail to know
- Heat shield not included — plan to reuse stock or buy separately
Reach for this if: You own a 2011-2016 GSX-R600 or 750 and want a straightforward sound upgrade that does not demand a tuner.
Look elsewhere if: You need a full system for maximum horsepower gains on a built engine.
2. STONEMEN Full Exhaust Muffler System Slip On For CRF150F CRF230F 2003-2013 Titanium
A 304 stainless system that weighs 3.1 kg and fits bikes from a 1984 ATC200X to a Hawk 250.
The pipe is 304 stainless steel, and the muffler can is 6061-T6 aluminum — a combination that resists corrosion well. Owners mention that the sound is much quieter than an old Cobra unit, with a straight-through design that flows freely without being obnoxious.
The trade-off is that fitment almost always demands creativity. One buyer installed it on a 2007 Lifan Xpect 250 and had to bend the header pipe four degrees, relocate the exhaust bracket, and use sealant on the joints. Another shaved half an inch off the mid-section for a perfect fit on an XR200R. If you are comfortable with basic fabrication and do not mind a Saturday-morning project, this is the best dollar-per-sound value on the list.
What you get
- Complete system with 304 stainless header and 6061-T6 aluminum muffler
- Straight-through design delivers clean flow and a pleasant sound
- Weighs just 3.1 kg; the SHARKROAD weighs 10.43 kg
What to expect
- Almost always needs bending or bracket modification for a proper fit
- 0.010-0.020″ slop at the muffler joint — sealant is recommended
Ideal for: A weekend mechanic who owns a CRF150F, CRF230F, Hawk 250, or a similar dual-sport and wants a budget full system.
Not for: Someone looking for a bolt-on that requires zero modification right from the start.
3. JFG RACING Dirt Bike Slip On Exhaust,Motorcycle Muffler Pipe Full Kit for CRF150F CRF230F 2003-2017/TAO TAO TBR7/HAWK 250-Red
The pipe that turned a Hawk 250 from a 60-mph struggle into a 75-mph cruiser.
This is the same 38mm connection diameter as the STONEMEN system above, but buyers consistently report a more dramatic power gain. One verified owner wrote that their Hawk 250 went from struggling to hold 60 mph to maintaining 75 mph on the highway — a jump that makes the bike usable on faster roads. The sound is described as moderately louder than stock, with some calling it “insanely loud” on a TTR125.
The construction uses aluminum, stainless steel, and titanium materials, and the welding earns consistent praise for a budget part. Do note that this is not a USFS-approved spark arrestor, so if you ride in national forests that require one, you will need a separate screen. For pure power-per-dollar on a Hawk 250 or a CRF230F, this is a strong contender.
Why riders like it
- Hawk 250 goes from struggling at 60 to maintaining 75 mph after install
- Quality materials and welding for the price
- Adds an aggressive MX sound without being overbearing
Downsides
- Not USFS spark arrestor approved — check local trail rules
- Fitment may require a rubber bracket extender on Hawks
Best for: Hawk 250 or TBR7 owners who want a real seat-of-the-pants power increase on a budget.
skip it if: You ride in areas that require a spark arrestor equipped exhaust.
4. JFG RACING Full Slip On Exhaust Muffler – Complete Exhaust System For For CRF150F CRF230F / Hawk 250, Titanium
A 38mm connection diameter full system that one RPS Hawk 250 owner says sounds like a 450.
This is a close sibling to product #3, but sold as a complete system with an aluminum muffler and a stainless steel pipe. The muffler length is 430mm, and the same 38mm connection diameter applies. A 2024 RPS Hawk owner reported that it fitted no problem after fabricating a small bracket for the silencer, and the engine pulled cleanly through the top end after the swap.
One 2003 CRF230F owner mentioned that getting the slip-on fully seated took a strong second pair of hands — the muffler needed to be lifted into place while the bolts were tightened. The stainless tubing itself bolted up with no leaks, and the owner had the system on the bike for six to eight months with no issues despite a few drops.
Highlights
- Complete system — header, mid-pipe, muffler, and hardware
- Better throttle response and pickup reported on Hawk 250
- Durable stainless tube resists leaks after months of use
Watch for
- Muffler can be a tight fit to the mounting tab — a helper is helpful
- Bend angle may be off for CRF230F, requiring bracket tweaking
Go for it if: You own a CRF150F, CRF230F, or Hawk 250 and want a ready-to-run system with good reviews for sound.
Think twice if: You expect a perfect bolt-on with zero bracket or alignment work.
5. 35mm Exhaust Muffler and Pipe for 150cc 200cc 250cc Dirt Pit Bike Scooter Motorcycle
A 35mm connection diameter universal pipe that is a gamble on fitment but a steal if it works.
This is the most affordable option on the list, and the price reflects its universal nature. The 35mm connection diameter is 3mm narrower than the 38mm units above, so it will not match bikes designed for a 38mm mid-pipe without an adapter. One reviewer noted the header pipe was cut two inches too short and that a plastic piece bolted into the muffler end risked melting, while another had no problems and reported good metal quality.
If you are fabricating a custom setup for a pit bike, scooter, or a 150cc-250cc project where you can weld or use a flex pipe, this is a cheap way to get a muffler and a header. If you expect to bolt it onto a stock bike in ten minutes, this is a high-risk purchase.
What works
- Very low entry price for a muffler-and-pipe combo
- Some customers note good metal quality and no fitment issues
Major risks
- 35mm diameter may not match your bike’s stock pipe
- Several reviews report header too short and poor seller support
Only grab this if: You are building a custom project and already have the tools to modify or adapt a universal pipe.
Stay away if: You need a direct fit for a stock engine without fabrication.
6. SHARKROAD Super Loud Version Chrome 4″ Slip On Mufflers Exhaust Pipe for Harley 2017-UP Touring
A 10.43 kg no-baffle muffler set that makes a Milwaukee 8 sound like a Harley should.
These slip-ons are designed for 2017-2023 Harley Touring models, and they ship with no baffle inside — you get the full straight-pipe volume from the first start. Reviewers point out a 30-45 minute install on an FLHP, and the sound is described as louder than V&H slip-ons that cost three times as much. One owner replaced V&H mufflers with these and said the stock radio was still audible on the highway, which is a good sign for bagger riders who want noise without sacrificing communication.
The 2.5-inch inlet matches the stock Harley header pipe. At 10.43 kilograms per set, these are the heaviest mufflers on this list, but that is expected for dual chrome cans built for touring duty. The one-year warranty is a decent safety net for a budget-friendly Harley exhaust.
What it delivers
- Deep, throaty idle and a loud rumble under acceleration
- Easy 30-45 min install with basic tools
- Much cheaper than premium brand alternatives while sounding bigger
One thing to note
- No baffle means very loud at full throttle — maybe too loud for long highway days
Right for you if: You ride a 2017-up Road King, Street Glide, or Road Glide and want a loud, aggressive exhaust without spending +.
Maybe not if: You prefer a tunable sound with a removable baffle to dial back the volume.
7. M4 Performance Exhaust GP19 Series Slip-On compatible with 2009-2024 Kawasaki ZX-6R ZX636
The GP19 that gives a 2026 ZX-6R a blisteringly loud note without looking aftermarket.
This is the Kawasaki counterpart to the M4 GSX-R slip-on at the top of the list. The GP19 series is built from stainless steel with a durable black finish, and the fitment is precise across the 2009-2024 model range. Owners of a 2023 ZX-6R report that installation took about 30 minutes, and the sound is described as “extremely loud” even with the DB killer (the removable baffle) still in place.
One reviewer recommended using a servo buddy to avoid a check engine light, which is a common need when you remove the factory exhaust valve on modern sportbikes. The DB killer itself is very hard to remove — one buyer scratched the finish getting it out. If you want a sportbike slip-on that sounds genuinely aggressive and fits like factory, this is the pick.
Standout traits
- Precise fitment across 2009-2024 ZX-6R generations
- Extremely loud with baffle in — no need to remove it
- Black stainless finish looks clean and hides heat discoloration
Installation caveats
- DB killer is very difficult to remove if you want it out
- A servo buddy is recommended to avoid a check engine code
Reach for it if: You own a ZX-6R and want a loud, race-inspired slip-on that bolts on in half an hour.
Pass if: You are not comfortable with the possible need for a servo buddy or electronic bypass.
8. Vance and Hines 16672 Twin Slash Round 4in. Chrome Slip-On Exhaust for Harley Davidson Touring
A 4-inch chrome slip-on from a brand you can trust, with a signature twin-slash cut end.
Vance & Hines is among the most recognized names in Harley exhausts, and the 16672 Twin Slash Round delivers the rumble you expect. Buyers on a 2018 Ultra Classic describe the sound as a strong rumble at idle and a deep growl on acceleration — noticeably better than stock but not so loud that it drowns out the radio or annoys the passenger. The alloy steel construction with a chrome finish holds up well against road grime.
These are designed specifically for 2017 and 2018 Touring models, but one owner confirmed they fit a 2023 Road Glide without issues. The install took about an hour with 13mm and 15mm sockets, and the sound improves after the first 500 miles as the packing breaks in. At 23.8 pounds for the pair, these are on the heavier side, but the build quality is excellent.
Why it is a good buy
- Brand reputation with consistent build quality and sound
- Rumble at idle, growl on acceleration — not obnoxious
- Easy 1-hour install with basic sockets
Constraints
- Officially listed for 2017-2018 models only, though later bikes may fit
- Heavier than some competitors at 23.8 lbs
You want this if: You ride a 2017-2018 Harley Touring and value a proven brand with a sound that is richer than stock without being deafening.
pass on it if: You are after the absolute loudest pipe for an older Touring model outside the listed years.
9. Yoshimura RS-2 Comp Series Full System Exhaust (Street/Stainless/Carbon Fiber/Stainless) for 00-19 Suzuki DRZ400S
The full-system performance legend for the DRZ400 that adds a perfect growl to a 3×3 and jet kit setup.
Yoshimura is a benchmark name in motorcycle exhausts, and the RS-2 Comp Series is the go-to full system for the Suzuki DRZ400S. The pipe combines a stainless steel header with a carbon fiber end cap and a stainless mid-section, keeping weight low while improving flow. Owners say the sound is incredible but not too loud, and the bike pulls harder across the rev range when paired with the common 3×3 airbox mod and a jet kit.
The only real complaint from buyers is that a new manifold gasket is not included in the box, so you will want to order one ahead of time to avoid reusing the original. The fitment is precise for 2000-2019 DRZ400S models, and the instructions are straightforward. If you own a DRZ and want a complete performance exhaust that transforms the bike, this is the one.
What stands out
- Full system with stainless header and carbon fiber accents
- Perfect sound — more growl than stock without being offensive
- Ideal match for the 3×3 airbox mod and jet kit
What to prepare for
- Does not include a new manifold gasket — buy one separately
- Premium pricing reflects the brand and full-system design
Choose this if: You own a DRZ400S and are ready to do the 3×3 and jet kit mods to open up the full potential of a high-end exhaust.
it’s not for you if: You want a cheap slip-on for purely cosmetic reasons without tuning the carburetor.
Understanding the Specs
Connection Diameter
This is the measurement of the pipe opening where the muffler connects to the rest of the exhaust system. A 38mm diameter is common on many dual-sport and dirt bike exhausts, while Harley touring mufflers often use a 2.5-inch or 4-inch inlet. If you buy a 35mm system for a bike that expects 38mm, you will get an exhaust leak that kills performance and sounds bad.
Slip-On vs. Full System
A slip-on replaces only the muffler can, which changes the sound and drops weight without changing the engine’s air-fuel ratio. A full system replaces the header pipes and the muffler, which increases power more but often requires a fuel tuner or a jet kit (a device that adjusts how much fuel the engine gets) to prevent the engine from running too lean — an air-fuel mix that runs dangerously hot.

If you want the best value for a dual-sport like the Hawk 250, grab the JFG RACING Dirt Bike Full Kit for the real-world top-end gain. And for a Harley bagger seeking a premium sound upgrade from a brand you know, the standout is the Vance and Hines Twin Slash Round Slip-On.
