dose anyone know where i can get a list of tracks with the db requierments if thier isnt one a sticky should be made???

I don't know of one, BUT I do know that it varies based on the day of the week and organization for a lot of tracks. The location of the dB sensor also varies, making predictions further complicated.

Limerock is the only one I know of on the east coast with low db numbers (85ish for most days) and it is enforced.

85? Holy ****, my car wouldn't pass that with the stock/ITR hybrid exhaust

85? Is that with an OEM exhaust, and 20 pillows?

Thats just absurd.
Maybe instead of letting horsepower loose on the track they should just allow horses?

Each track has its own levels.
Calling each track and asking the track steward or PR person there will get you the answers your looking for.

The standard for measuring the noise levels is from 50 to 75 feet from the track in any given location.
Most of the devices are mobile, and the tracks do this on purpose to catch someone who might be pointing their exhaust away if they know where the device is at any given time.

Gather your information. Know what exhaust works for each track.
Bring ur extra parts in case you have to quiet things down.

I did alot or research before i bought my exhaust. Laguna Seca was my worry...
Now that i bought my exhaust i know i can quiet it down to meet those types of levels.

There was a thread that had to do with exhausts and different tracks. Search for it.
