Better Exhaust Flow. If your engine is working hard, like it does when used for racing applications, it needs to be able to release a lot of exhaust. With this Kooks 3 in. High-Flow Catted Y-Pipe, it can. Designed to improve exhaust flow, this Y-Pipe is legal everywhere except California.

Quality Construction. A Y-Pipe intended for racing and sports applications must be sturdy to withstand all of the challenges of wild roads and rough riding. That's why this Y-Pipe is made from strong stainless steel.
