Off road exhaust

[Locust Cutter]

Hey Brian-
I was wondering about your MBRP 4" off road, turbo back, straight pipe - is that a 4" down pipe or a 3.5" down pipe? I ask because I've been told that a 4" down pipe is hard to fit in an '04, but I have no experience with these yet, so I'm curious what I'm in for,... Either way I'll be ordering the full 6.0 solution kit + aforementioned exhaust + SCT Livewire (w/corresponding EGT probe). I appreciate your time in answering this,...

Most "4" turbo back exhausts" for the 6.0 have a 3.5" downpipe. A true 4" downpipe will require some extra cutting to fit.

I thought that was the case, but, I wanted to be sure before I ordered it. Thanks Brian!
