    Adam Rohrbach (Robes) | Friday, April 04, 2003 - 08:39 am  I was parked next to a friend at school yesterday and he revved me up just jokingly in his camaro. I did the same just being playful. He did it again, so i did it, just going to about 3500 rpm. When i let off, it made this high-pitched popping sound for about a second and included maybe 10-12 pops. It has 2.5" dual exhaust off a 3" downpipe. I am not sure of the problem, or if there is any. If anyone could help, it would be much appreciated |
