Right now I have the factory exhaust manifold down to right behind the o2 sensors, then 2 - 2" pipes join together into a single 2.5" pipe right where the main cat would have been. Then a 14" long glasspack where the resonator was, then 2.5" pipe back to a flowmaster 80 single in dual out 2.5" camaro muffler where the stock muffler would have been with tailpipes exiting at the stock location. I wanted to do duals all the way back but flowmaster does not make a muffler short enough to fit 2 in the factory location.
I ran the car with open headers - no muffler- for about 10 minutes. It was evil. I loved it but in about 30 more seconds I would have been deaf. I ran it with both the dynomax and flowmaster and no glasspack for a while (not at the same time). Very loud even when just putting around with either muffler but with the flowmaster it was a good loud in a v-8 kind of way. With the dynomax it sounded like a weedeater from hell. Way too loud to take a long trip in. Right now it is still loud but not tiring on long trips. It stays pretty mellow when just cruising around but it does get loud when its revved up.
