OK, off topic, but...
Way back, when the social security Ponzi scheme was first proposed, one of the big objections was that it would mean issuing Federal ID Cards to everyone.
They overcame that by printing "Not For Identification Purposes" on each card.
Pretty damn effective, wasn't it! New ones don't bother to say that anymore.
Funny how government works, aint it?

I feel like as long as you are not catless or have straight pipes and have excessively loud car you should be fine.

Q4 is relieving and Q9 states that it should be under 95db.

How many decibel would a SS sport be in an otherwise stock e46 m3 be at?

I'm assuming if you get a ticket and even though you are well under the db limit, you will still have to pay 1000. I don't think they will test the sound level when they pull you over correct?

So something like the SS street or sport could still cost you 1000 if the cop just wants to give you a ticket for a modified exhaust. I don't believe for a second some cops will not abuse this.

And does that also mean if you have say a CSL intake or any other intake that all needs to be swapped back to pass the inspection?

There's nothing more annoying than having to hear someone's excessively loud exhaust (and by loud I mean sh!t that makes your eardrums feel like they're about to rupture). So on the face of it, yes this does sound like a good idea if it is applied across the board evenly. This means going after Harley owners for noise citations too and not just car guys.

However, in real world practice, I think this will just give law enforcement even more reason to profile and target specific groups of people. If you're a minority driving a modified beater, WRX, or even our platform with anything other than a factory look, you're asking for trouble. But when a group of Harleys blow past city streets at WOT on a weekend in front of a coffee shop...somehow law enforcement turns a blind eye to it.

Fabulous!
Another VERY expensive infraction that can (will) be selectively enforced.

I agree with all of your points, especially this one.

A little perspective. According to one of the above posts, 95 DB is a commonly-used standard in California. As a comparison, in Europe the limit was 80 db since 1975, and recently dropped to 77 db.

One of the local tracks has a 96 DB limit, and most people aren't having a problem meeting that in the race groups. I'm running catless with a free flowing magnaflow muffler, and barely register 94 at full throttle.

The point is that most aftermarket exhausts will not run afoul of the law, and there is no need to run out and reinstall the stock exhaust.

And if your exhaust is so loud that you can't pass sound at a NASA or SCCA race event, then it probably shouldn't be on the street either.

Thank you, vwrado for posting that CHP memorandum.
We should all find the complete document and print it out for the glovebox. Might be handy if the cop is on the fence about writing.
