Not much chance of it being under 100db, I'm afraid... Under 105db, yes, but not under 100db, not without other work on baffling, additional silencing, either on the downpipe or bungs in the ends. I think there was a thread on here a while back about fitting bungs on a Japspeed... Not my cup of tea though. New downpipe with additional silencing would need to be done as a custom build from a good exhaust fabricator, although not sure how big a silencer you could slot in to be honest, and it would probably be easier (and possibly cheaper?) to just get a quiet custom cat back system made up if you were going to go to a custom fabricator anyway.

So, fine for 105db track days but not so good for under 100db days... But I have kept my stock back box for them!! :)

If you will be regularly doing track days under 100db, then prob best to get a different system.
