Pypes Performance Exhaust

Regular price $722.99 Sale

Systems come complete with an X-pipe, a pair of Pypes mufflers (Street Pros are standard), cad plated clamps and hangers. All systems feature mandrel bent, 16 gauge, stainless steel pipes. The combination of our crossovers and selection of mufflers delivers a perfect balance of sound and performance.

Our Special X-pipe allows the pipe legs to run in driveshaft tunnel in order to optimize ground clearance (2.5 inch systems). Customers can also purchase an extra pair of MVR200S and weld them in as resonators at the end of the tailpipes if quiet is of major importance.
