John,

Even though you will probably drop boost w/ the 3 inch exhaust, you may make close to the same power on less boost than you are making now. The engine has become more effecient do to the reduced exhaust backpressure, and at a lower boost level you may be able to run a little more agressive tune if the exhaust effeciency does not make all of the power back up from the expected boost drop, the tune might.

I guess what I am saying is I think you should learn the power you have now or will have w/ the 3 inch exhaust and perhaps a changed tune. 650-660rwhp is a TON of power. You being an mn6 car its going to be all you can handle at the track. My suggestion right now is start looking at things like tires and clutch after you put on the 3inch and retune. Get used to that, then look at more power and have the money saved for a fuel system and a motor fund when the 700+hp beast goes south. As others have said I think you are already pushing the BAP as far as I would be comfortable now or w/ the 3inch exhaust and retune. Anything more in my opinion to be safe a fuel system is a must.

With the right setup you have a potential 10 second car already. The key will be the setup of course and how well you drive it.
