I have a slight whistle noise when I am about 3k and above..it sounds like a turbo with a small amount of boost.. I was wondering if you guys think I may have a leak or is this a normal noise after a header,y pipe, and intake manifold port matching. There is no hesitation...but the car seriously sounds like it has a turbo....even the wife said so. Let me know what you think.

CAI, Header, Y-pipe, catback. No whistling noise.

Slight mostly couldn't even notice whistling from NWP intake manifold spacers.

Might be from the port matching you did?
