Had the AP recirculation valves installed on my 997 TT just a few days ago and they sound amazing ! actually beyond amazing, you can actually hear the turbo's whistle as you go through the gear and not to mention the sweet sound you get as soon as you shift on high RPM's. I'm gonna upload some pictures and video's of my car which has finished, finally, being modified.


"Thanks Dan"


Cheers.

 

Any performance or response gains?

 

Where is that video and pics brotha!
