It should be simple! I've got an exhaust leak between the head and header of my 2007 Electra AVL. I have draw-filed the sealing surface of the header and made sure that the header is drawn up tight with its flange nuts BEFORE I attach the muffler. Still, I get a leak of exhaust.I sure wish "they" used a nice, old VW-like copper exhaust sealing ring....any fixes out there??"Is it just me?"Bob
I just be really, really careful bringing the torque on
Now I'll have to get the dealer to figure out what make the copper gasket is used for, so I can order a spare!
the silicone sealer doesn't harden, so it's quite easy to remove the pipe at a later date. As for not having the muffler attached when you're tightening the pipe, it's a bad idea. Tighten the pipe and brackets before you try to seal the head as then it will be in the position it needs to be in. Doing it without tightening the attaching parts will result in high stress points as the other parts are trying the move head joint which can break the seal, or the pipe bolts. But pipe does need to be close to the position where it will finally sit, but not tightened all the way until last.Bare
