i mean run a 3" d.p. off the turbo go under the car with it. cut it off, no muffler

DO NOT do this for long. I have personally seen the damage this caused on a now poor partially charcoaled 337. If you are dumping, dump it away from the fuel lines, don't just lets it out straight. That exhaust is HOT.
But imho, leave your setup the way it is. The restriction you feel is not from the exhaust, it's from our tiny turbo's inability to keep up in the high revs.

if done properly, you won't have a charred car. i know some peeps on this board who have it done right, and have zero issues.

I'd like to see what a difference, if any, that a full three inch would do compared to the three inch down pipe to 2.5in all the way back. I run a 3in down pipe to 2.5in without a cat and I don't think I'm going to wring any more out of it with a full three inch.
