Smile Performance versus fuel mileage

Which exhaust setup is ideal for getting better performance and fuel mileage at the same time>? Or does such a combo exist? I know I want a turn down so the resonation gives it a deeper tone, but I want better throttle response too. Perhaps a cold air intake as well? I have no idea which combo to go with any advice is appreciated. Thank you

Don't know about the exhaust, have not done that yet. I did put on the K&N Aircharger system last spring, they claim 10HP increase. As for deeper tone, you'll get that, but it will all be up front since you remove the factory air box. At half to WOT it makes quite a rumble.

In my experience, the exhaust is part of a system that helps you improve performance and mileage.

The other parts are a cold air intake and a programmer.

No programmers are available for your year truck yet. CJD encrypted the PCM software and no one has been able to get past the encryption yet.
