Oldengineer Contributor Posts 392	05-11-12 07:31 PM - Post#2224994 Good luck - hopefully you'll be able to get the other 2 bolts out as well. On my car, I had to replace my original exhaust manifold. A previous owner had put a home made dual exhaust set-up on the car. To do that, some one cut a hole in the exhaust manifold in front of the original opening and welded on a foot long piece of inch and a half water pipe. Then he welded pieces of various shapes of exhaust pipe to that to connect it to a second exhaust system on the other side of the car. Welded solid like it was, the joints had started to crack apart. Took me several hours with a sawzall to cut it in 4 places to get the mess off the car. I wondered why the car didn't seem to run right with the dual setup as well. I found out when I got the buggered up exhaust manifold off. Whoever did it, left the metal slug from the hole inside the exhaust manifold and it had mostly blocked the original downpipe hole. The car runs way better now - with a single exhaust system. If you end up having to drill and tap the holes, be sure and get a good drill bit and tap. Regards: Oldengineer
