One last question before I spend...

SLP loudmouths are a little bit tougher to find than some exhaust products. I bought mine directly from SLP.... www.slponline.com

I have sound clips of me reving and being a loud ass @ my website (in sig.).

If you decide to do an X pipe you'll need the O2 extension harnesses due to the placement changes in the 04s. Good luck, and good choice :nice:
