    More throttle response. A little bit more free breathing. Maybe more psycological than actual direct performance feel, but getting more air in to the engine and getting more out (exhaust), is never a bad thing!

    I have done it and would do it again.

    I personally couldn't tell much of a difference however I think it would be more noticeable with more boost and rpms (8300+)
