Just notice because I have my exhaust on but wanted to make sure this is normal. Foot on the clutch put into first and rev it to 2 1/2 3rpm while the car is stopped and my rasp from my x pipe is gone (best way to describe it) take my foot off the clutch and Rev it to 2 1/2 3rpm and the rasp is back and it feels like the throttle response is back. Is this normal?
