So lately I've been noticing a rattling/buzzing noise coming from my exhaust. After take out the heat shield that hangs out above the muffler I realized that is was actually the muffler make the noise. So I took the muffler off to figure out what's going on and I noticed a gap between the canister itself and the pipe running through it. Now I'm trying to figure out if this is normal or if the two pieces used to be connected and have rusted so much they separated.
Check out the pic
That circle is around the seperation between the canister and the piping. Anyone have any idea if that is supposed to look like that or not?
Thanks for the help,
Justin
