DPF back exhaust
 

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.

it wont help. :hellox:

If it does it will be very little

They don't help. The factory muffler isn't very restrictive at all.
I put one on when my tailpipe rotted away from the muffler :D

Yep they very rarely change anything.

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?

nope b.s there is nothing inside no louvers but you can dang near by a full system for the price of a cat back just sayin:tu:

get a dpf delete and and a 5 inch turbo back man
