Where do I get this muffler cement? Rite now the muffler sealant from advance auto is working but incase it fails I want alternatives. Is this muffler cement like plumbers putty or flu goo?

 

Pretty much. Not sure where Ray gets his.... (where I first started using the stuff.) I think you should be able to get it at the parts store, but, not entirely sure on that... I will find out from him when I am there today.

 

i looked at advanced and pep boys and just found that same sealer that I used. The exhaust is holding for the most part but I had a couple little leaks. The main problem is where i cut a coupler to make it fit its leaking like craazy. All i can figure is I need a 2-3/4x2-1/2 to make the muffler fit to the tail pipe, sense the chinese cant make a difference beteween size in 2-1/2 od and 2-1/2 id. on the reducers that are 2-1/2idx2-1/2 od they just make the one size more like 2-1/4. I put a 2-1/2 id piece next to a 2-1/2od piece and the ends were the exact same size. This was at pep boys and advanced. Well thats my complaining for the day

 

never had a problem with jb aand heat,,,, hell u can use it on blocks

 

The red Permatex muffler sealer works better when it is applied to the pipe before installing it into the mating pipe and then clamp it, and let it dry before starting motor.

 

I've definitly had JB weld burn off and fail before. When it starts to burn it smells horrible also.

 

anyone else have anything about this exhaust cement?

 

Dude, your looking for some miracle cure, and that simply is not going to happen. I understand the financial part of your problem, believe me.

 

the putty stuff worked on my down pipes off the headers untill I replaced them. stunk for about a week though... but its rated up to like 400 degrees...the key is prepping the surface so it sticks..

 

Don't buy a $100 stick welder, you'll drive yourself nuts trying to learn how to use it.

Get an inexpensive Flux-Core (MIG) welder, it's not much more money and with about a day of practice you will be good enough with it to be able to run a bead and seal up your exhaust properly. Harbor Freight or Northern Tools have them for not much more $ than the cheap stick welders and you'll be amazed at how many fixes and little projects you'll use it for after you have it.

I learned on a 220V stick welder, still have one, but use my Lincoln 140T 110v MIG 90% of the time when I need to weld something...
