so my brother brought home a decibel meter tonight...

sooo we measured my exhaust level. now i've always found it pretty reasonable. the magnaflow catback tames things down. anyway, here's my findings:

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.
