I have Flowmaster A/T on my 94 GT, it sounds good but with the 4 Cat H-Pipe its not that loud.

I have found that the Cats make the biggest sound diff out of the whole exhaust system. On my '83 I started it up with just the MAC PRO Chamber, man that was sweet. It almost sounded like a big block. But in my friends '89 when we started it with the 4 Cat pipe and the 2 Cat pipe it just didn't have the deep grunt the O/R Pipe (PRO Chamber) did.
