im getting my super 40 installed next week. its a 3" in dual 2.5 out. im doing straight pipes and i have 3" tips. should i get 2.25 inch pipe or go with 2.5. what about back pressure loss with larger tail pipes
It's not back pressure that you'll lose, its velocity. As long as it's after the muffler, you'll be fine with the 2.5". The single 3" is perfect for these trucks. :imo
