Ok, Well i have a problem with my car. I have a 2001 mustang v6, K&N FIPKII, Flowmasters True Dual Exhaust. When i go to accelerate fast on it it starts to like make very quiet popping noise out of the muffler. I can notice that it feels like it is chugging when i give it gas too. If i drive very slow nothing happens. The sound does sound like it is coming from the rear.
The car has 62,000 miles and it is a automatic
