Exhaust upgrades
The first mod on almost every build. A slip-on trades the stock muffler for sound and less weight; a full system replaces headers to tail and chases actual power. The ladder runs from a $250 budget slip-on to a full titanium GP-style system.
The short answer
Slip-on = sound, weight savings, and the look, for the least money — power change is minor. Full system + tune = real gains, at real cost. If the pipe is for your ears, stop at the slip-on and spend the difference on suspension.

Exhaust by model
What each bike's page says about exhaust: the brands that fit, the year splits and the gotchas, quoted from the 42 bike pages that have a note on it.
Honda CBR600RR
Yoshimura and Honda go hand in hand — RS-5/Alpha fitments are everywhere used. Full systems delete the servo-operated exhaust valve: fit a servo eliminator or flash it, or you'll carry an FI light. C-ABS bikes route differently at the rear master — check exhaust clearance notes for ABS models.
Kawasaki ZX-6R
M4 is the ZX-6R default — the same brand the race paddock runs — and the value pick. Arrow full systems are community-reported to out-power the M4 on the 636; Akrapovič is the premium ticket. Any full system orphans the servo-operated exhaust valve: plan a servo eliminator or a flash.
Suzuki GSX-R600
M4 is the GSX-R default — GP and Street Slayer slip-ons, and the GP full system the club-race grid runs. Yoshimura is the other natural pairing. A full system deletes the SET servo valve, so budget a flash or servo eliminator with it.
Yamaha R6
Graves is the Yamaha race specialist and the pairing you see in US paddocks; Akrapovič is the premium pick, M4 the loud-for-less option. Full systems delete the EXUP valve — plan a flash or servo eliminator in the same order.
Aprilia RSV4
Akrapovič supplies the factory race-catalog systems; SC-Project GP70-R is the aftermarket signature. Fitment splits hard at 2021 (new bodywork and routing) and 2019 (1100 vs 999 in the same showroom). Decat without a tune means CEL plus servo faults.
BMW M1000RR
Stock is already an Akrapovič-built titanium can, so slip-ons gain little — the real step is a full race system (Akrapovič race line, SC-Project) paired with a flash. Systems are M-specific at the tail section; S1000RR listings don't automatically apply.
BMW S1000RR
Akrapovič builds BMW's own accessory mufflers, so it's the default; SC-Project and Austin Racing are the loud alternatives. Full Ti systems cut roughly 8–10 lb. Fitment splits hard at 2015 and 2019 — a K46 system will not touch a K67. Removing the stock exhaust upsets the servo; pair with a flash or servo eliminator.
Ducati Panigale V4
The Akrapovič full titanium race system is the canonical V4 purchase — it deletes the underbelly cat, sheds claimed double-digit pounds, and requires the matching map. SC-Project and Termignoni are the alternatives. Slip-ons are a sound-and-looks play here more than most bikes.
Honda CBR1000RR
Yoshimura is the US Honda staple (deep fitment catalog, slip-on to full race), Akrapovič covers SC59/SC77/SC82 at the premium end, and SC-Project trades on WSBK association for the RR-R. Full systems on the SC77 want a flash to fuel correctly.
Kawasaki ZX-10R
Gen 6 forums run long Arrow-vs-Akrapovič full-system debates — Arrow is the value pick, Akrapovič the premium one, M4 the US-garage staple. Full systems orphan the exhaust servo valve: budget a servo eliminator or a flash alongside.
Suzuki GSX-R1000
Yoshimura and M4 are the Suzuki-native choices; Akrapovič and SC-Project cover the premium end. Full systems delete the SET servo and the under-engine cat — a flash is effectively part of the purchase price.
Suzuki GSX-R750
M4 is the GSX-R default and Yoshimura the classic Suzuki match — both make 750-specific systems. Do not buy a 600-marked full system: headers differ even though everything else on the bike looks identical.
Yamaha R1
Akrapovič full titanium is the benchmark; Arrow is the value full-system pick straight out of R1-forum consensus; Graves is the US Yamaha race shop choice. Any full system means EXUP servo elimination — flash at the same time.
Aprilia RS 660
SC-Project CR-T is the signature look; Akrapovič, Arrow and LeoVince cover the ladder. Read listings carefully — the cat lives in the mid-pipe, so 'slip-on' vs 'full decat' changes both sound and whether you need a tune. Full systems without a flash throw a CEL.
Ducati Panigale V2
Termignoni is the heritage pairing and comes with a matching up-map when bought as a Ducati Performance race kit. Akrapovič and SC-Project are the aftermarket regulars. On the 959, check your market first — US shotgun mufflers and Euro underbelly systems take different hardware.
Honda CBR500R
Slip-ons listed: Yoshimura R-77 (Street 2013–2015, Signature 2016–2025), Akrapovič (2013–2015; carbon 2016–2026), Two Brothers M-2 (2013–2015), Hindle (2013–2015; 2016–2024) and Hotbodies MGP (2013–2026). Full systems: Hindle 2013–2015 and 2016–2022. Hotbodies states its slip-on does not eliminate the cat.
Honda CBR650R
Full systems only in the listings we checked: Akrapovič's Racing Line (titanium, 2019–2024) and Hindle's Evolution and Evo-Megaphone systems (2019–2026). Akrapovič lists O2-sensor fitting kits separately for 2019–2023 and 2024–2025, and states the Racing Line does not meet street or highway emission requirements. Honda revised the ECU and catalyzer for 2024.
Kawasaki Ninja 650
No slip-on is listed for 2017–26. Akrapovič, Yoshimura, Two Brothers, SC-Project and LeoVince sell full systems only, and Kawasaki's US accessory catalog has no exhaust. Those makers list slip-ons only for 2006–11 bikes. Akrapovič's approved Racing Line keeps the cat and needs no remap; its track system requires one.
Suzuki GSX-8R
Suzuki's catalytic converter sits in the mid-pipe, followed by an under-chassis chamber and a short right-side muffler. Akrapovič (Racing Line and homologated systems, 2023–2026) and Arrow (Works homologated with catalytic converter, Works racing, Competition EVO) list systems, as do LeoVince (LV-14 R) and Yoshimura (AT2). Homologated systems include the cat; Akrapovič's GP system, LeoVince's LV-14 R and Arrow's Competition EVO are listed as not street-legal.
Suzuki SV650
M4 is the SV650 signature pipe; Two Brothers and Delkevic cover the budget end, Yoshimura the polished one. Systems are generation-specific — gen 2 headers and gen 3 under-engine cat routing do not cross.
Triumph Daytona 660
Only full systems are listed: SC-Project (STR-1 Euro 5 approved; S1 and CR-T for racing) and Akrapovič's Racing Line (closed-course only, no remap needed, a check-engine light on Euro 5+ bikes, stock 8.0 kg against 4.72 kg). Neither lists a slip-on.
Yamaha R7
Akrapovič covers slip-on and full-system; Graves builds the Twins Cup race systems and is the paddock-credibility pick; Yoshimura and Two Brothers cover the value end. Full system wants the flash — the CP2 runs lean without it.
Yamaha R9
No slip-on is listed for the 2025–26 R9. Akrapovič, Yoshimura (AT2 Speed and Race series), SC-Project and LeoVince sell full systems, and a retailer listing titled 'slip-on' for an SC-Project SC1-R is a full system. Akrapovič's Racing Line comes two ways: EC/ECE-approved with the cat and no remap, or track-only with no cat or pre-muffler and a mandatory remap.
Aprilia Tuono 660
SC-Project, Akrapovič, Arrow and LeoVince cover the 660 platform; many systems carry joint RS 660/Tuono 660 fitment but not all — the underbelly routing is shared, the tail is not. Full decat wants a tune to avoid the CEL.
Ducati Monster
Termignoni is the factory-adjacent choice (Ducati Performance kits pair with an up-map); SC-Project and Akrapovič are the aftermarket staples. Slip-ons keep the cat and pass as sound mods; decat and full systems commit you to ECU work.
Ducati Streetfighter V4
Akrapovič full titanium is the marquee system; SC-Project and Termignoni compete. Slip-ons are tame by design — Euro noise compliance — so riders chasing sound end up at full systems with the map. The underbelly cat is the same 'shoebox' story as the Panigale.
Honda CB500F
Akrapovič lists three CB500F slip-ons (2013–2015, 2016–2018, 2018–2025). Two Brothers M-2 lists CB500F/X 2013–2015, Yoshimura R-77 CB500F/X 2013–2014, Hindle CBR500R/F/X 2013–2015 and 2016–2024, and Hotbodies MGP Stinger CBR500R/F/X 2013–2026. Hotbodies states its slip-on does not remove the cat.
Honda CB650R
Akrapovič carbon slip-on is the signature CB650R pipe (typical street price around $600); LeoVince LV-10 is the budget favorite; Arrow and SC-Project make fuller systems. The underslung 4-into-1 means 'slip-on' is muffler-only — buy it for sound and weight, not power claims.
Kawasaki Z650
Vendors list full systems for the 2017+ Z650: Akrapovič (Racing Line 2017–2020 and 2021–2023), Yoshimura (AT2 2017–2026), LeoVince (LV One Evo 2017–2024), Hindle (Evo Megaphone 2017–2018), Graves (2017–2019) and Arrow (X-Kone 2021–2022, Indy Race Evo 2024). The only slip-on we found is Arrow's X-Kone (2017–2022). Most are sold as not street-legal, Graves' has no O2 sensor bung, and Arrow's homologated Indy Race Evo (2024–2026) includes a catalytic converter.
Kawasaki Z900
The Akrapovič carbon slip-on is the default Z900 look and drops real weight; SC-Project S1 and Yoshimura cover the alternatives. Note the big pre-chamber under the engine: slip-ons keep it (modest sound change), full systems replace it — and then you're committed to a tune.
Suzuki GSX-8S
Suzuki's catalytic converter sits in the mid-pipe, followed by an under-chassis chamber and a short right-side muffler. Akrapovič (Racing Line 2023–2026; GP and homologated systems), Arrow (Works homologated with catalytic converter, Works racing, Competition EVO), LeoVince (LV-14 R, LV Race) and Yoshimura (AT2) list systems. Homologated systems include the cat; Akrapovič's Racing Line and GP systems, LeoVince's systems and Arrow's Competition EVO are listed as not street-legal.
Triumph Street Triple 765
Arrow makes the exhausts Triumph sells over the parts counter, which makes it the no-drama pick — dealer maps exist for them. SC-Project and Akrapovič cover the premium ladder. Full systems split at 2023 (new headers); slip-on fitment often spans more years but verify per listing.
Triumph Trident 660
Competition Werkes lists a slip-on for 2022+ ($650). Full systems: Akrapovič's Racing Line (2021–26; closed-course, no remap needed, a check-engine light on Euro 5+ bikes), SC-Project's STR-1 (Euro 5 approved) and race systems, LeoVince LV One EVO, ZARD and Scorpion. Triumph revised the catalyst and silencer for 2026, so confirm fitment for that year.
Yamaha MT-07
Akrapovič's full titanium system is the canonical MT-07 exhaust; SC-Project brings the louder Euro flavor and LeoVince the budget entry. Decat and full systems routinely set a check-engine light without fueling work — plan accordingly.
Yamaha MT-09
Akrapovič's low-mount full titanium is the classic; SC-Project for the Euro sound, Graves for US race pedigree. Decat work sets codes without a flash — budget them together.
Honda Grom
Yoshimura, Two Brothers, Hindle and Tyga all make Grom systems — almost all are full systems, and every one is generation-specific (4-speed vs 5-speed headers differ). Loud is easy on 9.7 hp; pair any pipe with fueling to actually run right.
KTM 390 Duke
Akrapovič slip-on (KTM PowerParts catalog) is the aspirational pick; Remus and LeoVince cover the mid tier. On 2017–23 bikes the 'slip-on' replaces only the end can — the cat and main silencer sit under the engine, so treat exhausts as sound-and-weight mods unless you're doing header-back work.
Kawasaki Ninja 300
Akrapovič (carbon fiber slip-on), Two Brothers (M-2 slip-on and full system, plus Tarmac full system), M4 (standard-mount slip-on) and Hindle (slip-on; stainless and Evo Megaphone full systems) list 2013–2017 exhausts. Yoshimura lists a fender eliminator, muffler bracket and offset brackets for this bike but no R-77 slip-on.
Kawasaki Ninja 400 & Ninja 500
Slip-ons (Yoshimura, Akrapovič, LeoVince) are sound-and-weight mods — no exhaust servo on this bike, so no fault lights. Real gains need a full system plus a flash, and even then this is a momentum bike; racers buy the full system for weight and ground clearance as much as power.
Kawasaki Z400
Slip-ons are listed by Akrapovič (2019–26), Two Brothers (2018–23), Coffman's (2018–24), Yoshimura's AT2 (2018–26) and LeoVince's LV-10 (2019–23). Kawasaki lists the Akrapovič as item 124878 ($748 MSRP) on its 2019–21 Z400 pages. Akrapovič sells a carbon slip-on with a street-emissions warning and an EC/ECE-approved titanium one; Kawasaki's listing doesn't say which you get.
Yamaha MT-03
Slip-ons: Akrapovič (2016–26; the carbon one is EC/ECE and Euro 5 approved), LeoVince LV-10 (2015–26), Two Brothers (R3 2015–24 with MT-03 2020–21) and Coffman's shorty (a separate 2025–26 SKU). Full systems and de-cat pipes (LeoVince GP Corsa, Akrapovič Racing Line, Coffman's de-cat) change fueling.
Yamaha R3
Yoshimura and Akrapovič slip-ons are the common picks; Graves builds full race systems from its MotoAmerica program. Expect sound and weight savings, not meaningful power — it's 321 cc and honest about it.
