OUTstanding! That's exactly what I hoped to hear.

As for where I did my tests, it was at an intersection on a road near my apartment. (That's my friend that was helping me...)


Unless you start factoring in objects and other variations from a "perfect test site", a site that needs no modifiers was somewhat challenging to find. I borrowed the dB and should have already returned it; I will be returning it this coming week.

If anyone is able to get a hold of another dB meter, I'd be happy to help set everything up and do the tests with you.

The following link is to Title 75, Title 67, Chapter 157 of the PAVC. It gives all of the test specifications if you want to see them for yourself. (I think I have them all commited to memory by now. lol)

A lot of the dB measurements taken from exhausts that are out there were taken at the tailpipe. This GREATLY changes the results.
