APR X-Pipes

For vehicles with a 3 in. mid-pipes and an APR cat-back exhaust system, the APR X-pipe is a must have. This upgrade creates a smooth transition between the two systems and integrates an X-pipe that reduces backpressure. The crossover pipe also smooths out the exhaust note for a more refined sound profile, while increasing peak torque. Like the rest of the system, the X-pipe is constructed from T304 stainless steel, with beautifully Argon-back-purged TIG welding throughout, and includes all-new APR slip clamps.
