i've been lookin around for a good uppipe/downpipe/exhaust combo for my STi, and so far i've found that a lot of people go with Helix, Helix, and Apexi GT Spec.. i dunno, i've seen one in real life and i like the sound and stuff, but does that draw the most performance? tell me what u guys got on ur STis, and if u like em or not, and the price range?

thanks alot

 

i dunno about sti
but i have helix up and down pipes on my 03 and i absolutely adore them
