Duals all the way from the headers back or just dual mufflers? The stock tbird exhaust runs two into one at the resonator and then Ys back to two at the rear of the car. Was your exhaust stock prior to installing the flowmasters?
I'd also like to know the answer to this question. If it is stock y - single - y duals then the flowmasters aren't going to sound nearly as rowdy as if it was duals from headers all the way back. I've been through a few different setups with my bird. I'm finally happy with how it sounds right now, but will likely have to quiet it back down once I get Kooks headers.
