Small crack in muffler.

[Hayes]

I noticed a small (~1.5" long) in the underside of my Flowmaster yesterday. Looks like it took a rock hard enough to crack it slightly. I haven't noticed any change in sound--but then again the Flowmaster is not necessarily quiet.

I'd hate to see it get worse through corrosion, etc.
Is there some kind of bandaid-like fix?

Clean it off well and then JB weld away.....

you could also bring it to a muffler shop and have them weld the crack, should only cost $10 so, cheaper if you know someone with a welder
