The procedure is SAE J1169. Unfortunately I couldn't find a copy of the procedure. You can get one from SAE for like $50, but you could probably find somebody that has it if you look around.
It seems the test specifies 95db at 20 inches, static load. That's pretty loud, but not super loud. I don't remember your SRT4 being that loud. 118db is loud!
Here's a guide for relative noise levels. (Pay attention to the distances!)

A power lawn mower is about 95db. So that's what the allowable loudness at 20 inches from the pipe would be (as I understand from skimming on the spec). 118 db is like a jet taking off at full power just a couple hundred feet away. So I'm skeptical your car is that loud.

Ugh haha this is complicated. I'm skeptical of that myself... At least with the stock exhaust. The prior exhaust setup would definitely have been too loud but we're not talking about that one...
Any idea what rpms they should be testing at?? They tested me at 4050 rpms
