I just looked over my local tracks rules. They say all street driven vehicles must have mufflers? How strict are other tracks? Anyone raced at Sears Point(Infineon Raceway)?
I have never had them enforce it with the trucks
Won't race Infineon Raceway until Pinks all out or I should say Pat will be racing.
I do know that the announcer yells over the microphone when a truck puts out too much smoke.
