Exhaust decibel data

[vex]

I'm looking to give the RCC a nice leg up to throw into the RCC membership tool box. I'd like to ask those that are willing and able to purchase a decibel meter (one can be had for your Iphone for $2.00 or free if you look hard enough, or from radioshack for around $50). I'd then like you to record your exhaust decibel in nuetral fully warmed up. Here's how it will work:

Measure back 6 feet from the center of your rear wheel. Have some one place the decibel meter on the ground inline with the exhaust and stand opposite of your exhaust pipe and the meter. Get in the car and record the Decibel reading at idle, 2000, 3000, and 5000RPM. If you'd like you can also do a nuetral rev and take the Peak Decibel value you receive.

(This is when it gets tricky) Record what kind of exhaust you have. If you have stock you can simply state 'stock'. If you don't have a 'stock' exhaust system state the style of exhaust you have. IE:

Racing beat Universal 3in Presilencer to Dual Magnaflow 2.5in perferated packed mufflers.

NOT Magnaflow XL3 mufflers (though that information may be useful, the muffler type is more important).

Further more those that go to the Dyno often (I'm looking at you TTT), can record their exhaust decibel levels under load for even further information.

You may be asking yourself what's the point? This seems like a lot of work and no immediate gain.--And you'd be right. The immediate gain would not be there, but the future gain would be extremely useful in getting new products made, or finding better products to help gain performance over 'stock' while not causing our ear drums to bleed.

This is how I envision it to work:
You're in the market for a new exhaust system and would like to know exactly what to look for before picking it up. You know RB is an awesome way to go but you don't want to deal with the price tag that's associated with it. So you come to the RCC toolbox and look at the exhaust numbers (don't worry I'm sure we'll come up with a better title for it later). You are then presented with actual numbers that represent the decibel level at a specific distance from the exhaust exit. If stock has a decibel profile of say 70db, 80db, 82db, 90db and you know you want to stay close to those numbers you can easily look at others individual set ups and see that another individual has these types of muffeling devices installed and has the following decibel profile; 75db, 82db, 85db, 92db. Wham bam you record the muffeling device type, order the parts you want, and are on your merry way to more performance.
