wow i feel you... i had a HKS on my DC2 for like 3/4 years and passed by cops no problem and one day a cop pulled me over because it was too big
500$ ticket / had to get smog test / had to go to police station to get it check and signed ticket / go to court and see a judge and plead guilty.. about a 600$ ticket after
thats california for you.. thats why im a bit hesitant to get a exhaust still.. im going with a dual stock exhaust style like stock... i dont want a can exhaust type where cops will get an eye on it
