muffler sounds

Has anyone ever heard or put on a 1 chamber flowmaster on your blazer? im just wondering because i have a 2 chamber on, but have a 1 chamber sitting in my house and wonder if its alittle too much...any help would be great. also, the spair tire is now like wedged in there because the pipes rap around it, any wait to fix this problem?

I have put a one chamber magnaflow in my blazer....I don't know about the sound diffrence between the one/two chamber mufflers.... but my truck is definitly the loudest exhuast around aside from harleys.
