high flow cats INSTALLED
TRAVIS08 : We need a Soundclip!!!!!!!!!!!!!!!!!!!!!!!!!! I've got straight pipes already so hi flows added might make it a touch loud in everyones opinion? I like the sound of the straight pipes what would have to be done to add hi flows and keep a similar sound???
That part number will fit a 97-03 5.4. You can also check out Troyerperformance.com I think they also recommend that part number for our truck.
I have gibson on my 05 and am curios. Let me know how it sounds!
