Need a 3" exhaust system, but are concerned about the fit around your shocks and/or gas tank? With plenty of flow to handle the horsepower and a fit that rivals OEM, the new Pypes 3” Hybrid systems combine the best of both worlds. These 3” Pypes Hybrid Systems use our 3" X-Pipe technology and a set of custom (3" in to 2.5" out) mufflers connected to a set of 2.5" mandrel bent tailpipes. These kits are complete with all the required 3” to 2.5” components to get you from the cross-member back with ease. All components are constructed of 409 stainless steel and backed by our limited lifetime warranty.

These systems are the way to go for higher horsepower vehicles that have out-grown standard 2.5" systems, but suffer from serious tailpipe space limitations. Pypes Hybrid 3” System design allows for optimal flow while the OEM style 2.5” tailpipes provide ideal fitment. The increased volume through the 3" X-Pipe and 3" Mufflers means better engine breathability with more torque and horsepower. The 3” Hybrid design releases backpressure and scavenges the exhaust through the X-Pipe, this creates a higher velocity of flow that results in increases to your car’s overall performance
