Does your m3 ever get a fluctuation at idle for about 10 seconds, then stops? Ours goes like +/- 100 rpm's at 1,000 when it starts, cold or not, then stops...
I'm looking to pick up the SuperSprint race muffler for my M3....but i think i'll be adding a rasp terminator of some type. do you have any other videos of your set up? curious about rasp....

No videos yet, although not as noticeable as before there is definitely rasp. You either like it or you don't.
