I have all bolt on's so I wouldn't recommend running the stage 2 til you open up the exhaust all of the way (at least thats what I was told by VAC and Pro-Tuning Freaks). You will want more than just the downpipes before switching tunes.
I have AR designs catless downpipes, Agency Power mid-pipe and corsa exhaust, Evolution Racewerks FMIC
Thanks for the info. Apparently only the 1ers need different exhausts to run those tunes. But I plan on keeping stage 1 aggressive until I get intercooler and dp's then it'll most likely be stage 2 aggressive. Leaning towards vrsf for both fmic and dp's.
