Having a real hard time picking AM products for my resently purchased 05 sti. Mods for now r turbo back exhaust,BOV, and intake.I know u guys have probaly heard this a thousand times but its tough when ur on this end of it.. Thinking of the tanabe turbo back wondering if anybody has one on there sti that i can hear and some better pics of it. That would be very appreciated, also thinking of the KN. Thoughts?As far as the BOV I'm stumped because talked to guys that have the HKS and it set off the CEL and I just cant handle that. Thoughts? After Im done doing all this will i have to get a diffrent map to faten it up because im pushing alot more air in and out? Thoughts? Really appreciate in replys
