Performance parts upgrade but still smog legal?
 

I was wondering if you guys could tell me some performace parts (cold air, exhaust...etc.) that I could use on an RX-8 and still keep it smog legal.

Thanks
Alan

Cat-back exhaust, intakes... that's about it. There is some debate as to whether or not you'll actually get any performance out of those things on an otherwise stock 8 though.
