Is Anyone Running Stacks With The Dpf Still Installed? And Is Anyone Making A System Like This For The Mega Cab?

 

Theres a used truck down at the local dealer that has a 6.7 and DPF in place. He just took off all the exhaust behind the DPF, and split it to each stack...

 

I took of my muffler off and put on a 4" tip dumpped, it turerd my tip tan from it burning the chrome from the excessive heat

 

I ran dual 5 inch stacks with my dpf on for almost three months. It worked great, no disoloration or anything like that. The diamond plate cover is an absolute must though and be very cautious of the things in your bed. I had one of my floormats melt right to the x-pipe. So besides the heat its fine. Didnt warp my bed or anthing crazy like that.
