I got pulled over back in 2002 for loud exhaust when mine was dead quite, even had a stock tip!!!! You know you are in trouble when the guy is 6'4", body builder, a cop, mush have a very little dick!
Anyway, guy was a total jackass, I explained I never drove the car on the street(99% true) was on my way to retire that day from the USN(true) and the guys I worked with asked me to bring it in(true)
Two damm loud harleys went past and I asked him why they were let go when we could not even talk while they were passing, he just got pissy and brought out some goofy rule book with photos, a cope of a new law in the city(that makes every dime it get's on the Navy and tickets on Navy people) had to pop the hood or go to jail, pics taken, car ran perfectly clean, etc.
Then I had to remove it all, back to stock which took two days, drive 50 miles to a referee, pay $150 or so, get it passed, go to see the judge, got a years probation, drove home and put my damm turbo right back on!!!!
Up in very far No CA, not smog checks, now registered in a small town in OR with no checks, moving to Portland area, will just take my chances as my cars run clean, commy bastards in government be dammed!!!
Now you know how I really feel
