BAD SVT
Addicted CEG'er
hey guys. i've got a quick question. I've had two different ppl tell me this. but i never paid em any attention. i was messin' around a while ago with another car. all he saw were my tailpipes. anyway, i digress... he caught up with me at the next light and said i had sparks going off in my exhausts. i chucked it up to just foolish games. however, i had someone else tell me the same thing after a couple of runs. anyone know what causes that? if it was running rich, wouldnt the fuel have burned off after the headers? does backpressure cause it?
