my truck has a exhaust leak at a large flange between the 2 cat converters right under the passenger seat. does any one have experience fixing this issue? i put a new gasket in it this spring but i could see light through the seem when i had new gasket in and the 3 bolts tight, so i took it back apart and put the original 24 hour cure jb weld on both sides of the gasket and put it together with that on it. let it set for 24 plus hours before using it. it worked for a little while but is pretty well all blown out again now. does any one have a good way to fix this issue more permanently?
i thought about cutting off the 2 flanges and splicing it all together with pipe but the pipes have such a large size difference and the one cat is basically welded right to the flange that i couldn't think of any good way to do that.
i could try just jb weld and leave the gasket out and see if that would hold?
i also picked up high temp jb weld i could try but it has a lower temp range than the original jb weld that i used the first time around
im pretty sure that 2 gaskets will never fill the gaps and the one auto mechanic i talked to said that wont last either.
would like to get it fixed, i couldn't believe how quiet the truck was after i got it sealed up this spring.
