Less than 10 rwhp and some better gas mileage most likely.

not sure but i can say its a good mod. i have LTs, CAI, exhaust and UD pulley and put down 370 rwtq and 365 rwhp with an m6......usually CAI lts and exhaust get you around 345-355 so im going to venture and say 10rwhp is a good estimate.....also easy to do yourself if you have the right tools, should only take about an hour nd a half
