I got word from a friend that Socal cops have a trailer parked off the 55 south freeway exit and numerous exits off the 405 north and south. Not much we can do with aftermarket exhausts but watch out and drop your car into neutral if you see them. Neutral helps a little.

 

aftermarket exhaust are legal in california as long as u pass smog, that means many higflow cats will pass the smog. If it is the sound level then all the aftermarket exhaust will pass them including HKS. 95db is very very loud and u will not achieve that sound unless u strait pipe the car from header back.
Let them stop me, i will slap the exhaust certification on their face and tell them not to waste my time again.

 

I know I meant that its about the sound, its not that hard to get an exhaust ticket. They have a trailer, Im sure that they could pull u over and test ur car in neutral at WOT parked. Im just puttin the word out, alot of people are turbo and heavily modded down by my old neighborhood of newport beach.

 

Don't get me wrong im not saying u should not look out but a lot of people have this misconception that if they have an exhaust it is automatically illegal. The testing method must NOT exceed more than 4500rpm, they can NOT WOT in standing position.

The smart thing to do is to get a exhaust certificate and not worry about cops stopping u for the sound.

 

Eh, I have something to worry about if they stop me

Anyhow, I find myself to be a casual driver on most days.

i read that it was a Pilot project to target Gross polluters and it measures with a laser your emission levels. if found over levels for now it only suggests that you take your car in for service. Guess if they find a lot It Will Go Beyond a Suggestion. I've seen this on the 405fwy in the south bay area of Los Angeles, I've also seen the mobile dyno on the street next to Echo Lake around last thanksgiving. Cops stand out facing the street and pull you over to dyno test. Lots of beater cars & some modded cars pulled over.......

 

Elaborate on how to get a certificate that you
re talking about. I'd love to have one...even if I put my test pipes on

 

The problem with exhausts is not regarding emmisions, its regarding loudness. Sure, it could be well under 95 DB, but according to the law, it's up to the cop's judgement on whether he fines you or not.

They have one set up in the Riverside area off of the 91 on the on ramp of Arlington, they've been there for a few days.

 

i know about the sound problem, I started this thread lol come on now read up top. I dont think theres a certificate, just one from HKS that says its within range. It doesnt mean the cop wont give you a ticket. They dont even need a sound testing device.

 

Replacing the cats is completely illegal, unless the OEM pieces are broken or damaged. Even if HFCs pass the emissions testing, the pure act of voluntarily changing them out can get you a heavy fine.

 

Wasn't really directed toward you or anyone one in this thread. Just felt like saying that

Be glad they are at least testing before giving you the ticket, saves you the time it takes to get certified. Also the ref told me they don't care what mods you have as long as it's safe they will run your car. I had a non carb legal intake and they said nothing, but they refuse to run a civic that didn't have enough engine oil. With the cops testing might be a different story...

You certainly can cheat the test and get the cert, but I don't want to ruin a good thing.

 

haha make them prove that you didnt damage the stock cat (s) and had to replace them . So easy to get around that. I have megan test pipes but they look like HFC's, I know they dont sound like them or smell like em

 

Damn, I wish I could go and get the certificate. But, even though they told you they didn't care for the mods you had, well, test pipes is a whole different story. It would suck if I went to get a certificate, and came out with a huge fine
