Our exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.

This is a 4" downpipe back race exhaust system for the 2001-2007 Duramax Trucks. This will replace the restrictive OE exhaust system with a 4" high-flow straight pipe exhaust system. This kit doesn't include a muffler and is intended for track applications. Just like all of our exhaust kits, it will come with all the required clamps, pre-weld contour bent hangers, and stronger flanges to help you sail through the installation process. It not only sounds great but will also improve mileage, torque, and throttle response.

Shipping

Free US shipping — no tariffs, no import fees.

Returns

Unused parts in original packaging may be returned within 30 days of delivery. Tuners married to a VIN need a factory unlock first — text a tech.
