Ive heard 25-35 hp for longtubes. Not saying that is what you will gain though.

you would see better results if youd had a meatier cam and heads. Id say around 15-25
Youll probably lose 1 MPG but at least your exhuast will sound awesome at WOT!

I agree with 15-25, 25-35 is a little high.

As far as total power, should be somewhere around 300rw with those mods, maybe slightly more for a M6.
