If anything, without significant improvements to the handling of this car you wont be able to take full advantage of the power we already have.

Based on this, I don't think it's worth it.

I have his old exhaust system with the cutouts. I've opened them up during my last 2 autocross events. Its loud, but not TOO loud... I still have my stock downpipes so...

Anyway, I opened them up less for power, more for the reduced backpressure on the engine, hopefully leading to a slightly cooler running engine. Right after my runs I see oil temps reaching 270+.

No from the exhaust. DPs unbolted from the turbo sounds horrible.
