I recieved a ticket this morning on my way to work for my (exhaust system modified too loud). I was on Hwy 101 here in California and I was cruising at 65mph, passed a CHP sitting on the side of the road, when about 2 miles down the road I see his lights go on and he got behind me. He comes up to the window and states don't worry you weren't speeding but your exhaust system is too loud. He then proceeds to tell me that any system modified from stock form is illegal. I am wondering how the law reads and if this is true then probably 60-75% of people should be getting these tickets? By the way I now have a Bassanin catted x-pipe and an SLP loudmouth catback.
