Does this (Summit turbo muffler) suck....sound,performance wise??? And the answer to the age old question....flowmaster or dynomax...one on each pipe!!!!

 

If you're looking for performance, or a throaty rumble, i'd stay away from these mufflers. I had them on my 82 Z and other than the cam shaking the car, you could hardly tell the car was running. They didn't seem to any more power than the $20 mufflers, i buoght from midas.
