Exhaust/Catback opinion question..
Exhaust/Catback opinion question.. I have a Flowmaster American Thunder catback on my car right now which I know is not the best when it comes to catbacks. The overall condition of the system is pretty good. I bought the car with this exhaust and the previous owner welded the intermediate pipe to the over-the-axle pipe. My question is........should I replace the Flowmaster muffler (5" x 10") 3" in/dual 3" out with something else (i.e. Dynomax Ultraflow welded, etc) or should I just buy a MagnaFlow catback instead? I have a MagnaFlow catback on my '04 Silverado (with Longtubes) and I love it. If I went with a replacement muffler over the catback, I would want a muffler that is quiet/moderate during cruising/normal driving but has a nice rumble when WOT. Any opinion is appreciated.

orangeapeel, Stainless Works and Dynatech both make them in stainless with catted 2.5" Y-pipe. Pacesetter also makes them with ceramic coating and 3" off road y-pipe. I have the Stainless Works on my truck. Very well made and the fit is perfect. Thinking about them for my Camaro over the Fall/Winter.
