What exhaust setup do you have anyway? I had a Supersprint straight center section with a Stromung muffler a while back and I would set off 5 or 6 alarms in my parking garage just by starting my car. I've fired it up with only headers and downpipe and it is DAMN LOUD...way way louder than the SS/Stromung setup.
If you are running anything that resembles a reasonable muffler, even if you have a straight center section, you probably aren't over 95dB. BTW, all I can find about the test is that it's stationary and is not meant to determine maximum sound levels. If you want more info you have to go the the SAE website and download the procedure for 59 damn dollars!
Do you mean to say that only factory parts may be used on a vehicle's exhaust system where you live? Are there Midas mufflers there? Meineke? They don't have factory parts. They make their own.
I have never heard of such a thing. You must live in communist China or something because a law allowing only factory replacement parts anything goes directly against free enterprise, competition, and the capitalist system, not to mention the useless and arbitrary restriction of personal choice.
You might want to double check the "law." I think Officer Jackass was just writing you a ticket that he hoped you wouldn't contest. That's what happened in my case anyway.
i'll get my sound decible meter out and test how loud the car is. BTW, my car is VERY loud, the loudest M3 i've heard.
anybody fire up there car w/ only the headers? i haven't measured, but i'm guessing about 10db less than that!
I've seen probably 50 E30 M3's, stock 2.3L, modded 2.3L, 2.5L and none of them have been as loud as mine.
where should i measure from? i'm going to measure from behind the car, directly behind the muffler, 45 deg off from it, and probably 5 feet away from it. i'm also going to measue from inside the car in the drivers seat.
I'm thinking of taking measurements at idle, a blip of the throttle, at 2500rpm, 5000rpm 10000rpm (just kidding) then while inside the cabin do the same and also at 60mph, 80mph.
i'm also thinking of taking a vid/audio of the testing, just to validate it's my car.
oh btw, i can set car alarms off by just starting the car! also i can make the windows at taco bell shake violently when i rev right next to them in the drive thru (the sound bounces of the wall and makes it sound awsome)
ok, i'm rambling now
