Tim, you're still missing the point about these being street driven cars. NHRA cars are race cars. You keep recommending that people break the law and remove their cats. That is not wise advice. And most of the tests that I have seen and referred to were done by independent testers and had no association with one of the cat manufacturers. Your car must have had a bad cat. Does that make all of them bad? No. In the end, is it worth the risk of losing the car and paying a large fine because you removed the cats to pick up 5 hp? There is a big push going in CA right now and they're yanking cars off the street left and right and people have to pay a fine($1000-1500) and then make the repairs to be emission's legal before they can re-register and get the car back. Is it worth it for 5 hp? Not if you have to drive the car to get to work. If it's a race car then it doesn't apply since it won't be driven on the street. If you're gonna remove the cats you might as well yank the EFI and put a carb on since your setup is illegal.
