EVERY TIME IVE BEEN PULLED OVER FOR EXHAUST/TINT I WAS DRIVING NORMAL AND HAD MY WINDOWS DOWN. SHIT I WAS AT THE BEACH SITTING AT A LIGHT AND HE PULLED ME OVER FOR EXHAUST AND MY CAR WAS IDILLING AND I HAVE THE GREDDY SP2 WHICH IS PRETY QUIET AND HE ALSO GAVE ME A TICKET FOR "INSUFFICIENT TIRE TREAD" B/C I HAVE ABOUT 2" OF INNER CAMBER WEAR ON MY REAR TIRES. SO I DONT THINK IT IS IN THE WAY YOU DRIVE AT ALL BUT THATS JUS MY OPINION
