Once the resonator seam popped on my GTP, I had it cut out and the U bend taken out at the same time. I thought it sounded pretty good and the cabin drone was not what I felt was too bad.
Mufflers gave out last year and had a local shop (same one that did the work above) put a couple of HP stainless mufflers. Real pretty polished stainless ovals (Stealth) with some baffles in them (not straight through tuner style round boys). Funny thing was I had to have them put a resonator in, cabin drone was real bad. Guess the stock mufflers were still muffling even though they had holes in them. New mufflers have a lower growl compared to the stock cans.
Magna Flows sound great on V8's not sure about a 3800.
Oops got that wrong, the TA has a Flowmaster, anyway, sounds great on the V8.
Mufflers are tough, easy to say "I don't like it" after it is all welded in place, just sucks to have to pay to change it.
