exhaust leak is making me mad

hey people,
I've developed an exhaust leak behind my flowmasters. it is where the hanger was welded to the pipe itself. all it did was crack the weld and pull away the piping. roughly the soize of a dime. i don;t notice it often, but with the wondows down and at a stop i can hear it and it annoys me. is there any good way to fix it? I've tried the fix it taope, and some sort of a mineral based paste with no luck. i can get to the hole but not to tape it well because the hanger is there and attached to the other pipe.
How much do you think it would run me to have the local muff shop weld it up for me? If i try to arc weld it i know I'm gonna burn through the thin pipe....tried on my last truck. it'll cost about $13 in gas to take it back to the shop i got it done at and I'm not sure if I'm still on warranty for it or not. thanks for the input

Re: exhaust leak is making me mad

You need to call around to the local exhaust shops. I have seen shops that want to charge $50 just for a minor hole, but I got my muffler welded in for $20 at another shop. Point here is that shoping around is the best thing unless you can get it free with a warranty. If for some reason you decide you don't want to have it welded anymore, I have an idea (may not work, but it did on my friend's). Break the hanger the rest of the way off. Then go get an exhaust clamp $3.00. find some suitable sheet metal (if possible 1/2 of an old exhaust pipe). coat the inside of the sheet metal with lots of JB weld. Clamp the sheetmetal with wet JB weld on it to the pipe with the hole. then ark weld the hanger to the clamp. Kind of a cheesy fix but it did work. I would recommend doing it right though.
