For vehicles with an APR Race DP and APR Catback 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. This upgrade smooths out the exhaust note for a more refined sound profile while also increasing peak torque. Like the rest of the system, the x-pipe is constructed from T304 stainless steel, beautifully TIG welded, and includes all-new APR slip clamps.
