Race Cat

IMO, it depends on if your state has emissions testing. If you do, and don't want to have to wory about putting your catalytic converter back on each time, I would say go with a hi-flow cat. But if your state doesn't, or you have a way around it, I would say go with the test pipe. I've had one on my car for about a year now and have no complaints. My exhaust is louder, the engine light has stayed off, and my car definetly feels less restrictive.

In a Naturally Aspirated DSM I'd race the test pipe, a cat can actually move.

That is quite possibly the funniest and most original bash at the 420A I have ever heard. Thank god someone is at least willing to put the effort into good quality shit talking .

Yup, that was the funniest thing I might have ever read in my life, back on topic, gut the cat or go with the test pipe. You'll notice the biggest gain. chris
