We're very please with the results on the 458 tune+exhaust package. The power gains were respectable 42WHP, but it was the exhaust note that impressed the most. Utilizing a true x-pipe design while maintaining the original triple tip layout, we were able to keep noise under control at low RPMs without the need for heavy and cumbersome mufflers and actuators, while getting that 'F1 pitch' at higher RPMs. Check the video out!
