How much did you pay for it? Did you get a HK BOV with it?drolander said:I installed the ATP Stage II downpipe today (downpipe + racepipe, no cat). It wasn't the easiest install, but well worth the effort. The hardest part was just getting the stock DP off (those locknuts suck). But the car screams now... it accelerates really fast and sounds awesome. I can't wait to get it to the track.
At idle the car doesn't sound much different from stock. But at WOT it is really loud, and there is more gurgling, etc. when letting off the throttle. I have a swappable cat, but haven't put that in yet.
I'll try to post some sound clips when I have a chance.
