decibel level

[snapper]

101 db tested with a decibel meter about a foot from the exhaust outlet. I borrowed a decibel insert like the ones Demon Tweeks sell and got mine down to 96 db, made the car run very rich though and nearly failed the emission.
Some have put a baffle in the pipe and used metal pan scourers, can be a bit embarrassing if they blow out part way through the test as the noise test comes almost last.
