Cracked Exhaust Manifold
Hey guys!! I have an exhaust leak at the exhaust manifold/cat assembly. The cats are built into the manifold and are clogged so I need to find a replacement. I called Lexus for a price and its just an outrageous amount of money. I can't seem to find an aftermarket manifold with the cats built in so I my only option seems to upgrading to a header unless someone knows where I can find an aftermarket manifold/cat assembly. Plus I don't think anyone actually makes a header to fit the 1st Gen GS. I think I would have to buy a N/A Supra header and modify the rest of the exhaust to fit. Any info or advice would be great thanks!!!

There are a few guys running headers on here if you search for them. Sadly I think one was just in a build up post so may be hard to find. You just run a cat directly after the header.
