Okay, now after reading about 10 threads about mufflers
I plan to call Lucien Donafro the owner of Arizona Exhast (602-415-9737) and speak with him about buying a pair of muffler shells inside which I can put either CC inserts or a 3 or 3-1/2" perforated tube or baffle... Thanks Ed for the contact information on all of those other threads!
