Everything you wanted to know about California exhaust noise
Enforcement Guidelines
The only drivers who should be cited are those whose vehicles:
1. are not equipped with a muffler
2. clearly emit an offensive, harsh, excessive noise, or;
3. have a clearly defective exhaust system (holes, leaks, etc)
Certainly seems like #2 is way overlooked and abused by most LAPD/CHP now a days, regardless of the dB levels.

I had that too but i had an hks hi-power silent on my wrx. The main reason for him to pull me over was license plate light. Then he saw my exhaust and gave me a fix it...
I have Apexi duel N1s with headers and i got pulled over yesterday for expired tags but they didn't say anything about my exhaust.
But just in case do you guys think the silencer Apexi offer makes a noticeable difference in sound?

I did however purchase 2x Apexi silencers for the N1's at the Apexi garage sale years back and they do make somewhat of a difference.
What do you think is better silencers or resonators?

To all above, except Poo

Side note, you can buy an inexpensive db meter at radio shack.
