Enhance the Performance

Upgrading your Dodge Cummins' stock exhaust with an aftermarket exhaust is one of the easiest ways to enhance its overall performance. Replacing your stock headers/manifolds with an aftermarket pair will assist in allowing your Cummins engine to breathe more efficiently leading to a drop in exhaust gas temperatures and a boost in horsepower and torque.

We have a wide selection of exhaust tips to choose from, and each is backed by free, live technical support and our Sinister guarantee. So pick your exhaust pieces and start enjoying everything that comes with a performance exhaust kit!
