I finally got a video put together of my '99 GT completely stock and then with SLP LM II catback. The camera got distorted alot by the Loudmouths, so its louder and deeper in person (which is usually the case with a clip). I used the same camera and tried to get the same distance behind the car to get a good comparison.
