| CHEVY/GMC 6.6L 4" & 5" SINGLE SYSTEM: |
 |
The Duramax has a refined toughness to it. MBRP Inc. has left the refined part to General Motors, and added extra toughness. The Duramax makes big power gains with this high flow 4" mandrel bent exhaust systems. Each system is a direct bolt on application and is manufactured as a full 4" system all the way back to the 5" diameter exhaust tip (Tip sold separately). Lower EGT (exhaust gas temperature), improved fuel economy along with more towing power are just some of the added benefits of having this system installed on the Duramax. |
