Anyone put stack on there 6.7 yet with the dpf. I was thinking just putting in a t and a valve so I can run stacks while sled pullin and for fun, but still have the stock exhaust also. I think a few people have this set up on there 5.9s. I know JD does he gave me the idea from seeing his truck.

 

I've done similar, go to http://buickgn.com/electricexhaustcutout.htm that's where I got my cutout. I have it on a Y pipe just before the muffler, and its just venting under my truck for now.

 

I just got a glimpse of the new 8 LUG magazine and it had a C&C I believe with a lift and 22.5 's or something and they were putting on an MBRP set of stacks. I didn't get to read much because the wife was tugging at my coat to go. Hope that helps you out.

 

Yes I read that issue, they just used a Y pipe off the DpF, Anything is possable just some imagination and you can do it.


Nick.

 

You would have to put your T valve after the DPF. Others that have tried running without a DPF and found their ECM de-rated the engine output. If you stop running exhaust through the sensors for the emmisions system the computer will de-rate the engine.
