I have some questions on Turbo II's. What is the widest set of tires you can stuuf in the wheel wells without and major modification? I was thinking about puting 245's or 255's in the back and maybe some 235's up front, with some 17'' wheels. Would this be possible? Maybe I should just get that awesome Mariah widebody kit. Also, does any here have Greddy Power Extreme exhaust on their car? I know its probably the most expensive exhaust available, but I downloaded a video with a guy that had it and it sounded awesome, not exactly the most quiet exhaust I've heard . I just wanted to know if you have it, are you happy with it? For some reason, they say it is the most quiet system they offer, well if that's true, I'd like to hear how loud the other exhausts they sell are!

if you want the most power and flow. go with the racing beat system. it includes and down pipe and presilencer and is 3" the whole way, where as the greddy is still only 2.5" at the cat flange. I beat the racing beat is cheaper too even though it's the whole exhaust. adding just a catback won't make much difference in power. but it's alot safer unless you plan on upgrading your fueling too, which you would need to do with the racing beat.

as for tires 255 is a nice squeeze in the back, and 225 in the front. on wider rims of course, no way you are going to fit 255's on the stock rims.
