The Duramax makes big power gains with the high flow 4" mandrel bent exhaust system. Each system is a direct bolt on application and is manufactured as a full 4" system. Finish off the system with a 5" diameter mirror polished exhaust tip.(optional) Lower EGT (exhaust gas temperature), improved fuel economy along with more towing power are just some of the added benefits of having this system installer on the Duramax.
