exhaust leak help please!!!

[beaver2489]

I got my 306 running today, but I got a bad leak on the passanger side header to x pipe collector. No matter how I position the x pipe before I tighten the collector bolts I still have a bad leak. I can feel the exhaust blow out quite a bit. Is there a sealant for this? Like the red silicone **** you use on rearends, but high temp sealant? Thanks

do u have the gasket for the header to midpipe connection?

You can try loosening the bolts, jacking up the xpipe EVENLY up till there is a fair amount of tension on the whole thing, and then tighten up the bolts. It helped a lot on my friends recent MAC equal length header install. (I personally will never get a MAC header, fit and finish was not the best)

i have a similar problem and i plan on going down to checker and geting a 2 1/2 exhaust gasket, it isnt made for our cars but ill just sandwich it in between them and i have a feeling it will work. i have heard other people on here doing that.

Permatex makes a high-temp silicone/copper sealer that you can use on exhaust.

permatex, thanks. I've tried every positioning technique to get it lined up right...nothing works. there just a little gap, but it leaks badddddd. I'll look into the permatex stuff, thanks
