I would not suggest removing the cat because your exhaust will sound raspy and disgusting, also it will ruin the environment. Instead, get a high flow cat from catco or carsound or randomtech.

As far as running rich, why? The preludes already run a little rich from the factory.

Anyways, do you have timeslips for your F22? I'm just curious as to how fast it is.

BTW, just looking at your sig, I'm going to recommend against the 3.5" dual exhaust and the flame thrower kit. Dual 3.5" is WAY too big for a prelude, especially a F22. And a flame thrower kit is just...fast and furious. I mean, it is your car so you can do what you want, but those are just my suggestions.

Good luck w/ your lude :thumbup:
