Thanks for clarifying for me. I have no idea what a fister 111 sounds like but I assume is not something I would consider. I'm looking for something actually relatively quiet at 70mph but louder when I'm on it so the stock one might be abetted bet for me.

This maybe a dumb question but why 3" tip? Better flow exit or is this just for esthetics?

Was planning to pick up a cat bypass for my '87, but was not sure if I would install a sport muffler or not. Can anyone comment on the sound level with a cat delete and stock muffler? Any louder? Rev better?

Your picking up a Cat bypass? Premuffler? Bypass pipe?

My M&K Premuffler gave the exhaust a lower tone, a better sound. Less poppy or chirpy. Rev increase is minimal but heat is gone. I like the sound but looking for a little more follow and volume.
