Use Leatherup.com motorcycle Exhaust Finder to search for motorcycle exhausts or exhausts components that fit your motorcycle. You will find stock (OEM) or aftermarket motorcycle exhausts. If you are replacing the entire stock exhaust system with an aftermarket system, you should have your motorcycle tuned - usually carburetor and fuel injection adjustment. Without tuning, your motorcycle may not perform properly and you can damage the engine. Cruiser riders are more likely to replace the entire OEM exhaust system. Slip-on exhausts (also bolt-on exhausts) are often used for upgrading a sport bike. Aftermarket motorcycle exhausts for American or metric cruisers are available from manufacturers like Cobra, Vance & Hines, Rush, and National Cycle. For sport bikes, you'll find aftermarket exhausts from Yoshimura, Tsukigi, Scorpion, LeoVince, and Two Brothers Racing.
