ok my exhaust sounds great, but right now, its about a 5 on the volume scale, and i want it to be LOUD, same quality, just turned up to 7 or 8...have any of you quad tip owners noticed that the actual hole the exhasut comes out of is only about 2 square inches, theres a black metal thing that makes a rectange, has anybody ever ported that out, or would that even make a difference, it seems like that would be extra backpressure...

I would do one of the following.
Remove Cat (02 Sims reqd)
Headers
Larger Pipe from cat to muffler
any one or all of those should make a significant difference in volume.99 3800 NBM Camaro - (Xcessive Xcelleration Racing Team)<br />Ram/Cold Air Induction (custom)<br />Modified 4l60e Valve Body<br />Z28 Catback<br />SS Hood <br />Modified 99 GM 3800II <br />JB Performance Engineering<br />jfbperformance@cox.net
