Exhaust
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 decision
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.
The brand ladder
Where each name sits on the shelf — market position, not endorsement. Brands appear because their catalogs cover this category.
| Brand | Tier | Origin | Note |
|---|---|---|---|
| Akrapovič | premium | SI | The full-titanium benchmark — you pay for the badge as well as the build quality, and the build quality is real. |
| SC-Project | premium | IT | MotoGP-derived designs, louder than most, priced right beside Akrapovič. |
| Arrow | mid | IT | The Euro value pick — full systems for well under Akrapovič money. |
| M4 | mid | US | Texas-built paddock staple; the default GSX-R pipe for a generation of club racers. |
| Yoshimura | mid | US | Japanese-rooted, built in California, with especially deep Suzuki and Honda fitment. |
| LeoVince | budget | IT | Entry-priced slip-ons that sound the part — a common first pipe. |
| Two Brothers Racing | budget | US | Budget slip-ons with a styling-first slant and a huge fitment list. |
