Message: i have a 2001 4.7 dakota. i just got my exhaust done. 3"pipe from the cat back into a flowmaster 40sereis dumped. :) :)
now my questions is ** i just bought a carsound hi-flow cat 3" in/out. would it be worth it to put 3" pipe form the y-pipe w/ the hi-flow cat into my 3" exhaust sytem?? i'm not worry about losing back pressure. can always get it back.
thanks for your time
