Bad muffler?

OK this is going to sound dumb,stupid,idiotic,not possible and I'm sure alot of other things but I swear my right muffler is bad. Sometimes it will backfire from the right side only. It sounds like decel popping but more high-pitched. I posted that I thought it might be having 92 gas in it when tuned for 93, but the concensus was this wouldn't be a problem. Happened on and off for about a weeks then was gone for about 2 weeks, but just the other day it has started again. Another odd thing is it happens alot when I go over a bump but also happens when I'm on a smooth road. I checked underneath the car and I didn't see or feel anything loose. So for now I have no clue what this could be.

You have an exhaust leak on that side. Tighten up the connections on that side and it will go away.

I know this from experience.

The drag strip is like sniffing glue, it's cheap, it's a decent buzz, it doesn't last long and they are all the same.
Road racing is like China White Heroin, the buzz is stronger, the high lasts for hours, it's extremely addictive and they are all different.
I can't wait for my next
