2008 DURAMAX LMM with MBRP Exhaust + Muffler Delete + Downpipe

A followup to my previous video, here the truck now has the whole straight pipe as well as the MBRP Muffler Delete pipe (30 inch piece of pipe delete the muffler) and the MBRP 3 inch downpipe. Now the truck is 100% straight piped right from the turbo. A slight hiss at the beginning while the vanes are positioning and then pure rumble. Hopefully I'll have some audio that I record with a microphone of the truck doing wide open throttle, because it sounds MAD.

did you use efi live to get rid of the his at idle?

[zackbennett]

@jjfan09 yes

Sounds great man! I just got a 3 1/2" DP to 4" to 6" mitre cut Grand Rock stacks puts on my truck. It will makes your ears hurt quick. I like listening to my 6.0L's VGT turbo change vane position, sound cool. Plus, the 03-early 04 6.0L turbos are a 10-vane turbo and are much louder than the 04-07 turbos.

Your Duramax still have EGR? I got the EGR of my 6.0L and couldnt be happier!

@Xx69roadrunnerxX I still have an egr yes, but it is blocked off.
