With the release of the LMM Duramax in 2007.5 model year applications came an entirely new exhaust system for GM. This factory system starts out at 3.5" diameter out of the turbo and features a catalytic converter, followed by a DOC (Diesel Oxidation Catalyst), and a DPF (Diesel Particulate Filter). Once the exhaust exits the last emissions device, the diameter is enlarged to a 4" diameter. If you're looking to improve upon the power and efficiency of your Duramax, we can help you upgrade your exhaust with a higher flowing 4" or 5" system built from aluminized or stainless steel in single or dual outlet, or even stacks!
We carry exhaust systems from AFE, FLO~PRO, Diamond Eye, MBRP, Magnaflow, Silverline, and Grand Rock. If you’re having trouble determining the best route for your exhaust system or components, feel free to give us a call or send an e-mail to [email protected] and we’d be happy to steer you in the right direction.
