i've done research, but anybody that knows cars, knows that the manufacurer says it will perform one way and it actually performs different than what they say. i just wanna know what people say who actually have them on their cars. but thank you.

4-1 headers give you more top-end. 4-2-1 headers give you a broader power gain. it depends on what you want and what your goals are. btw, don't waste your money on n/a upgrades for the beta, get a turbo. wink

yes, they are a direct bolt on. however, i would stay away from obx's products. i haven't heard good things about their exhaust, and the shift knob i got with their shifter is a pos. i have the mbrp exhaust, and i love it...great quality AND sound.
