Exhaust manifold exhaust leak

[buffbison]

okay... first off, i boughten onequickgt1's random technology catalytic converter, and i've finally installed it last weekend... and before i had installed it, i noticed there wasn't a donut ring aorund the catalytic coverter for the gasket...so i was thinking there really isn't supposed to be one...so i installed the catalytic converter anyway...so thats how i have the exahuse leak.......SO....a few days after that, i've bougthen a new doughnut ring gasket, and use that....still im having an exahust leak, and im not sure what to go from here... if anyone has a solution, please let me know...

thanks

(btw, the cc sounds awesome!)

I can't really follow where you do and don't have gaskets....but I'd suggest making sure there's properly sized gaskets between all flanges, and that the bolts are torqued down real good. I'd suggest using a graphite/metal gasket, they have more material to them, and won't blow out.....very nice gaskets.

For most Exuast stuff I just bite the bullet and take it in to an exhaust shop.

im still gonna try to **** with it some and find a way on my own, before i take it to a shop... if all fails, then i will.
