I have a 96 Gt i just put an o/r mac pro chamber on.The car has the stock manifolds on it, which will not be changed out right now.I have flowmaster super 40's welded in that have turn downs before axle.I like the sound at idle and easing along,but not when i get on it.At that point it sounds like a V6 in my opinion.What would be a good deep sounding cat back with the pro chamber?I want it deep at idle and when i get on it. Just a nice solid deep tone.And i don't mind drone.I actually like it.

 

I like my exhaust, BBK catted h-pipe and Origanl 40 series Flowmaster exhaust. I want to get another mid pipe without cats to make it louder ... Here's a video of my car taken this winter:

Sorry man but the prochamber is gonna sound like crap at WOT with any cat back. That is why mine is leaning up against the wall in the garage and an Hpipe is on the car now.

 

Well that just sucks.I was going to buy a regular h pipe at first then changed my mind.Thought the pro chamber would be better.
