Permatex Exhaust Repair Muffler and Tailpipe Sealer

Permatix Good quality muffler sealer,

The team came late

Has always worked very well for me. Had my exhaust system pipe re-welded and I was left with a small hole that spit exhaust out making a noise. Proper text, muffler, and pipe seal. Fix that very very well. Thank you.

The product was just great and worked as described. My main use was for around the Exhaust flange off of the manifold. I had tried installing a ring gasket on the flange which of course needed new bold and ultimately all bolts replaced and drilled through flange and even after bolt change the gasket would not seat with spring nearly all compressed to the max. I took back apart spread some sealer on the inside of flange both sides of gasket and the gasket too. Then squeezed it all together and it looked good, but as a precaution I added sealant to steel wool and spread it around the gasket and flange middle and in-between the bolts. Today it is still solid around the flange ( around 2 weeks) and I used the second tube to insert a new catalytic converter. I was struggling to fit the parts together which reminded me that I was going to use the sealant so I took it back apart and the reinsert other part of the exhaust and it held sliding the pieces together as well as assuring a better seal.

I had a pin hole in my radiator this worked

Permatex works! My muffler and exhaust pipe are sealed. No leaks!

It does a super job on a new installation. No leaks.

Got some nice Speed Engineering Headers but the connections are slip fit with clamps. No matter how you try, they would leak. I gave this sealant a try and it worked great. Cleanup is easy and you cannot tell the sealant was used.

The product came yesterday and have not yet used it, but I anticipate it will work fine.

Didn't work like I thought it would
