If you wanna both gain some power and torque,I think you'd better change the stock manifold,and keep the exhaust tip stock,then install a KN high-flow filter and do some ECU tuning,that's gonna help.

Akrapovic is nice but the price is way too high,I think changing a set of light weight rims would be a better option.
