the other day I went to a reunion of a bunch of guys with tuned cars. And they strted to rev the engines up, and this guy with a celica GTS 01 when he rev up the engine and he let the engine rev down sparks of fires came out of his exhaust. Not like fire, just sparks...
I couldnt ask him whatdid he have intalled in his car...
so I was wondering how is that possible, cus i have never hear from anyone with a celica with sparks of fire everytime they rev down
