Need to fix exhuast leak ASAP

Got a 91 S10 and I just removed the Cat convertor from the exhaust and my bypass pipe is leaking some exhaust. Not a huge problem, the noise just sounds like shit.

Is there anything I can buy to spray or wrap around the area its leaking from to eliminate the leak? Going to the Zone tommorow morning so I need something ASAP. Thanks

Unfortunately, there is no quick fix for rusted exhaust. You need to either get a new piece or splice in new metal. I'm afraid that is the only advice I can offer. When it comes to exhausts, the only fix is more metal, not quick fixes like tape because you will be making it harder for yourself when you have to re-fix things in a week or two. Hope this helps.

IT is not a rust problem. It is leaking where the new pipe goes back into the old pipe. Both are in good condition. I've been looking around and seen some exhaust wrap and/or Permatex sealants. Anyone used these?

If you are leaking where the "new" pipe meets the "old" pipe then you have a bad seal. Tape and permatex, which I use too, will not solve the problem. Just sand down the surfaces that join together and maybe they will seat properly. Otherwise, find another way to close the seal. This is the best advice I can offer for a leak which you already know where it is located.

Well, what is the best temporary fix and how long will it last?

A cheap fix would be to try some high temp silicone, but I don't know if that will work for you. I would try some sort of adhesive that is definitely very high temp, otherwise it will burn off. Hope this helps.

Hmm, JB Weld, think that would hold for a bit?

lol, I've used it before. I would say that if it works, great, if not, then you should've known nothing is as good as the proper fix. What have you got to lose though, except some time trying. JB weld does powder after drying, meaning it breaks apart and under heat I don't know what it'll do, but for your case.....I'd try it. Why not, nothing to lose. Cheap fixes is what I'm all about.

Thats my thing, cheap fixes are the best. Well I'm going to go to the Zone tommorow and pick up a couple of clamps and have a look around and see what I can find. Probably stop by CarQuest as well and have a talk with them since they tend to actually have knowledgeable employees. I will report back with my findings tommorow afternoon.

Didn't think about that with the JB Weld, but I'm not even going to bother with it.

Of course, putting the clamps on may take care of the job anyway, as it really isn't a big leak and I am putting (2) 2" clamps where one 2 1/4" clamp was (it was just a bit too big for the job) and once I tighten those down who knows.

Good luck then and I hope you find a solution. If both pipes are good then you need a filler of some sort, i.e. silicone, etc. They may give you other ideas too. I hope this works out for you.

Wait...filler? What exactly do I need, because that sounds like a good idea for me. Any kind of high temp silicone?

There are higher temp silicones that would "fill the gap", but if you are going to clamp it tighter.....That would be best. If you want to try silicone then go to the parts store and ask for high temp silicone that is good for exhaust applications. Can't cost much and worth a shot. How long it will last though, is another story. Noone can guarantee that one. Good luck.

Alright, thanks for your help, really appreciate it.
I'll post back tommorow with what I have found and applied.
