I have a new 2008 with this new 6.7 diesel fuel guzzler :$: and I was wondering if I pull the muffler off will it get a little noise out the rear of this thing despite the cat and DPF? I'm also hoping this will help mileage a little. 14 MPG is killing me. I bought this thing Feb 28th and I already have 10k on the odometer.
I gave my dad my 2005 with the 5.9 and 25 miles pr gallon....I think I goofed up.
Thanks.
Todd
