Although my car is otherwise 100% stock and my Evolve Stage 1 Tune, even that made a tangible difference. I recently flashed back to stock since I plan on dynoing this week or next and I quickly noticed the difference in driving experience.
I think what the Akrapovic Evo specific tunes such as the Evolve or ESS offer is improving and enhancing what the exhaust already does.
Have to agree. it improves and enhances, but is not "necessary"
Then again neither is this car ;-)
