i have 3 inches most of the way then it splits into 2 2.5s so it still flows the 3 inch easliy. I wouldnt trade down. Soon the turbo will make use of the flow.

Yes you will see a gain in top end HP running a 3in exaust. The only problem that comes with this is that you can end up changing your powerband. I would much rather have higher hp and torque #'s at 2500 to 4000 rpm then at redline. This is the RPM range that you are most commonly driving in and therefore would want to tune your powerband to give you the best numbers possible in this area.

actually we have had this this talk b4 about the size of the exhaust, and 3 inch would be fine, you do not need backpressure in a supercharged car like you do in a N/A car. This is what i remember from the previous talks so someone correct me if i am wrong

You are correct. With a forced induction car 3" is the way to go the pipe size is perfect for the application. Like I said I'm gonna try and be the first one to get the Exhaust kit from them. There setup looks really nice and I can't wait to see and get the finish product. Mark have you disclosed the type of exhaust to the public yet? Didn't wanna say cause wasn't sure if that was still under hush hush.

Trust me on this one, it's not that simple in a blown or turbo'd car. It's gonna benefit from the largest possible exhaust system. With the biggest area posible in the exhuast port/header area, once you get downstream of the cat, you can do some tuning, but the first 50-75% of the exhaust could not be too big, even with a 4" pipe.
