hi guys,
unfortunately i didn't pass my epa noise test coming in at 100dba at 4.3krpm. I think this reading is a bit suss because my personal db tester only read 87dba at 4.5k. My tester could well be out of wack and needs a calibration but it's besides the point. I need a stock turbo back exhaust so i can pass this test asap (and yes i tried the ol' steel wool method haha).
Thanks.
