Another exhaust question
My cats are totally clogged. I am sure of it. The vacuum of my engine is weak as hell, I have to rev to 5000rpm on every shift just to keep up in traffic, and my GTU tops out at 90mph, at WOT, going downhill.
The idle is fine, so I don't think that my engine is pooched, and the compression test shows a little low, but well within spec, and I can see smoke and huge amounts of heat coming off of the cats. The heat in the trans tunnel gets so bad sometimes that it surprises my fingers when I go to touch the shifter.
Question is, what is the cheapest way to eliminate the cats? I'm not looking for a super exhaust here, I just want the damn cats out from under my car!

Well, looks like I found the answer to my question: http://www.rx7.com/cgi-local/2catalog.cgi?cat=4&part=2
Are the symptoms I have typical of cat failure?

The header would make for some better noises. I don't really like the look of the brick manifold anyhow. I just can't see it flowing and scavenging too well, and it will probably become a bottleneck once I go supercharged.
