My SB 69 SS has correct 2" - 2 1/4" - 2" through resonators with transverse muffler. To quite! Would like to open it up a little but, don't want to loud.
Muffler is going bad so time to give it a little more of the muscle car sound-- without getting carried away. Also I still want to try to do this and keep it close to correct.
Any suggestions??
