Rule #1- dont buy a duramax.... ever.
Rule #2- dont bring it here. We dont work on that junk.

Did our yearly duramax fix to remind us why we really hate working on these rigs. This 14 locked the cp4 up, broke the injection pump gear to hell, and blew a hole in the timing cover... all at idle. We done a fleece cp3 conversion, replacement injection pump gear, and replacement timing cover. Got it running and operating again like normal.

This is a big post, alot of time has been consumed building these 2" primary-4" collectors full stainless hell cat headers. This ol heavy chevy should get up and go better with this power plant. We are doing full 4" dual stainless exhaust system incorporating vbands and stainless hangers as well. Should turn out very nice with a very unique exhaust note
