Just a couple exhaust questions. #1 - On a stock 08' Dodge 6.7, cat & DPF in-place, will a DPF back exhaust system do any good? #2 - I heard there are DPF back sysems designed to help with EGT's, is this true and if so who are they? Thanks in advance.
I appreciate the info. What about the EGT's, I read something, somewhere, about louvers or some sort of spacing placed at some point in the system that are supposed to reduce EGT's, I think to allow freash air to be pulled in. Anyone read anything about this?
