A list of new and improved traffic fines that went into effect in California, starting January 1, 2019, were published on the internet recently. When I tried to post them here in several different forms all I ever got was a "database error" message. I have no idea why that is. I even tried to retype them in my word processor, copy and post them in my message, but I still got the database error message and then it wouldn't let me modify and repost my message. So I will type this message "from scratch" and hope for the best, just concentrating on the fine for modified exhaust systems.
In the Great People's Republic of Kalifornia the fine for having a "modified exhaust" has been raised to $1000 "per stop". My brother is president of a 1970's "muscle car" club and he says that his members are running scared and few of them have the original exhaust and muffler installed on their 50-year old cars and most run cheap generic "glass packs". Oddly, he says that motorcycles are not covered by the modified exhaust fine. I have no idea why, unless it is because most "straight-pipe" Harleys are ridden by LEOs and prison guards.
