Ok heres the deal. My car makes a funny sound under light throttle and low speeds between 2000-3000 RPMs. sounds like a vac leak but I cant find it ANYWHERE. I have a topspeed cat back and Y-pipe with K&N typhoon intakes. Ive even gone so far as to have the flex pipes cut and straight pipe welded in. Nothing works haha. Do short ram intakes make a slight whistle sound?? if so then I wont feel bad, but my concern is its a vac leak somewhere. Someone please help diagnose this its driving me insane haha
