Well guys, no matter what I did to the OEM muffler, I did not like the sound. The noise level wasn't bad, just sounded terrible to me. Stuffed everything back in there, welded her back up and as good as stock, maybe quieter.
So reading on another forum (sin?), wrapping an aftermarket muffler will actually quiet down the interior noise in the car. So that is what I did. It is raining so I didn't take my clean car out of the garage yet to see the results. It does sound different when I rev it. Time will tell, and at the Dragon. James
