    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!

    you could just build your own and it would be cheaper.

    get the 04-08 design. It's the same thing as 97-03. the Stainless Steel option is a really good deal

    Big glasspack for a resonator. 26"+.

    Larger piping isn't needed, but 2.5" is very common.

    No need for larger tips if you get the correct 2.5"~ mufflers. Then it all fits.
