Has anyone ever ran a 30"x6" round bodied straight through magnaflow? I'm looking at a 5.3 '05 gmc with a flowmaster dumped. Looking for a stealthy setup and I think this enormous muffler might fit that requirement It's #12641

 

I had that one, its not as quiet as you would think. Its more like a diesel resonator than a true muffler.

 

Well that sucks. It is reasonably priced and should be somewhat mellow behind a stock catted 5.3. If not I guess I'll just add another muffler to the setup
