I got a pretty good price quote for a local custom exhaust shop in my area. I'm going with 2.5inch catback. With hooker max flow mufflers. I was wondering what inlet and outlet specs I need and if there is a preferred type of resonator I should use. I want to keep same exhaust tips I have just bigger (I have limited edition tips) I'm thinking 3inch I believe the LE tips are 2.5. Thanks for looking!
