Exhaust System Kits
About Exhaust System Kits
An exhaust system kit puts the pieces of the exhaust together in one purchase, from a full pipe and muffler to dual or slip-on setups. Riders shop here to replace a worn exhaust in one step, to get a different sound, or for a lighter, freer-flowing system. The listings cover a wide mix: systems for older ATCs, slip-on mufflers for the Maverick R, dual exhausts, and a few listings for road bikes, so read the title for the machine.
Check three things. First, how complete the kit is: a full system replaces the pipes and muffler, while a slip-on is only the rear part and keeps your stock head pipe. Second, the labels. Some are marked 49 State or Race Only, and Race Only parts are not meant for public riding areas where sound and emissions rules apply. Third, the machine: kits are made for a model and year, and a free-flowing system may call for new jetting or a fuel controller.
Brands in this category include S&S Cycle, Akrapovic, Pro Circuit, FMF Racing, Trinity Racing and DG Performance. Pick your machine in the Ride Finder at the top of the page. If you only want to change part of the system, see Silencers, Mufflers & Baffles and Manifolds & Headers, and for sealing the joints, Exhaust Gaskets & Seals. The full group is Exhaust & Emission Systems.
FAQs on exhaust system kits
What is included in an exhaust system kit?
It depends on the kit. Some are complete systems with the pipes and muffler, others are dual or slip-on setups, and the hardware included varies. Read the listing's description so you know whether you also need gaskets, clamps or springs.
What does 49 State or Race Only mean on an exhaust listing?
These labels describe where the part is meant to be used. A 49 State label generally means the part is not approved for use in California. Race Only parts are made for competition, not for public riding areas. Read the notes and check local rules.
Will a full exhaust system make my machine faster?
It can change power, but no gain is promised, and the result depends on the machine and how it is tuned. Gains usually come with a matched fuel setup. Many riders buy a system mainly for the sound, the weight saving or the look.
What should I check after installing a new exhaust?
Check that every joint is tight and not leaking, that the pipe clears wiring, fuel lines and plastic, and that the hangers hold it firmly. Some makers advise rechecking the fasteners after the first few heat cycles, so follow their instructions.
Can I install an exhaust system myself?
Many riders do, with basic tools and the maker's instructions. Take care to line up the pieces before tightening, use new gaskets, and check for leaks afterward. Hot exhausts burn, so let the engine cool completely before you work.
