the legal exhaust limit level is rediculous! we measured my exhaust by approximate legal specifications. 20 inches away at a 45 degree angle.

at IDLE my exhaust exceeds the legal limit by 1 decibel. from inside the car i can't even hear it. at 4500rpm(legal measurement is done at approximately 3/4 speed of where engine makes peak hp) it measured 126.3 decibels. approximately 8-9 times the legal limit. 5000+ rpm probably would've exceeded the meters range.

that law is rediculous haha. good thing it's not strictly enforced. thought some of you might find it interesting.

You sure it's 20 inches?
