    OEM exhaust manifold and aftermarket exhaust system with cat converter

    Need to buy the left manifold as my old one has a broken off mounting tab. My manifold gaskets are leaking so I plan to have them both replaced with ceramic coated OE manifolds, and install a new catalytic converter with mufflers and tailpipes (Delorean Industries Spec 1 stainless cat back $995 which includes the cat). Any suggestions would be greatly appreciated. I live in Irvine (SoCal) so prefer CA smog legal exhaust in case I sell it later.

    since you are in Cali, I recommend you keep all your old stock parts.

    I've heard that they are getting brutal about aftermarket Cats/exhausts, even if marked as CARB compliant. Best source for manifold may be any of the DMC shops, they always have tons of them leftover (especially outside of CA) after header installs from people who DON'T want to save parts.

    I have a Catalytic converter for sale in the DeLorean Parts section. It was removed from my car at 16,000 miles when I added the Stage 1 System.

    Thanks,

    I have an entire original exhaust system I'd be willing to sell. The manifolds and muffler were ceramic coated about a year ago and still look great.
    Cat is in great condition too.
