rx7-rage ,
you have all that and you still passed. that gives me hope. it thats whats causing your flames in the pic?
cause i want that. man that looks nice!

 

I got a race pipe (full cat replacement) on the parts car I bought from Blue TII a few years ago. I put it on my GXL for a bit and it was a fair bit louder, (not bad, pretty throaty) seemed to have more power all around as well as slightly better throttle response.
I'm getting rid of this pipe, as I now have a header w/bonez hi-flow cat. PM if interested.
