Speedwerx QO Series and L2 Series Stainless Steel Bolt-On Exhausts

These Bolt-On Exhausts are designed to increase power, add acceleration and throttle response, lose weight and give your machine a new deeper, throatier sound. With these exhausts, you are also eliminating the catalytic converter that is inside the OEM muffler- that means more air flow for better performance, and less heat retention for cooler engine compartment temps.

The QO (Quiet Oval) exhaust features a fully baffled design that is only slightly louder than stock and the all stainless construction means it's maintenance free. The L2 (Light n' Loud) exhaust has a smaller body for less weight, the straight-through design offers minimal restriction at a higher sound level, and the machined aluminum mounting brackets look trick too.

Both include everything you need to bolt on and go- the muffler, all necessary mounting hardware, and a powder coated aluminum "TURBO" trim plate to replace the stock plastic cover. They are an easy bolt-on installation with no other modifications required, but our Exterminator Kit will get you more added power and performance with our Torque Link ECU Tunes and Hypershift Clutch Kit to put the power to the ground- more details and another video on these coming soon!
