Hi, I got a notice in the mail about excessive noise, and having to get my bike checked by an approved noise tester. I'm hoping to get some advice on how to proceed. I have a 2000 GSXR600 with yoshimura trs exhaust. I've no idea how loud it is, but suspect it probably is a bit above regulations. I was thinking I would need to change to a different exhaust, but then found out you can purchase a low volume insert (TRS-INS-K). Does anyone know if this is likely to lower my exhaust volume enough for testing? Or are there any other options I should consider? Thanks for any help! Damian.
