Yamaha YZ250F Exhaust Systems / Mufflers

Pro Circuit's awesome T-4 Slip-On Exhaust gives you the power you need, with the light weight that you want. The body of this exhaust has been produced from 6061 T-6 brushed aluminum, and the end cap and intake are stainless steel, giving protection without adding a lot of weight. The end caps are tunable, giving you the capability of tuning the power delivery to suit your particular riding style.

FMF is well known for their exhaust slip-ons, too. The FMF Factory 4.1 Slip-On Exhaust uses innovative engineering to centralize mass and improve handling, and has an exclusive Chamber Core technology. It is available in an all-Titanium model, meaning its canister, endcap, and mid-pipe are all constructed from Titanium, as well as a stainless steel model that has a Titanium canister and endcap with a stainless steel mid-pipe. These American-made FMF exhaust pipes have performance tuning inserts and spark arrestor modules available. They meet all AMA sound requirements for most models, and if it doesn't, inserts are available to make sure that you are meeting all requirements.

If you are looking for an entire exhaust system, Pro Circuit, Vance and Hines, and Yoshimura have some great ones to choose from. Vance and Hines has a TI Pro Titanium Exhaust System that was initially produced for use by a factory race team. Now you can use the same exhaust system as the pros! This excellent exhaust system has been created from a titanium headpipe, midpipe, and muffler, which significantly reduces the weight that your stock exhaust system puts on the bike. Not only does this system reduce weight, but it also improves the horsepower and torque through the entire rpm range, and does so without exceeding the 99 decibel limit.
