As far as the tune making power with no mods due to changing the mapping of the A/F, I do not think the gains will be all that spectacular. Also keep in mind that some people buy exhaust systems for sound and aesthetics without caring about performance. On the flip side some buy just for performance. What I am getting at is buying the exhaust is an experience far beyond (JUST) performance.

Thanks, Tony
