I signed up for a track day at Laguna Seca where there's a 90db noise restriction in a certain area.

I wanted to ask if anyone has used the baffles or db killers in a Termi muffler for a 999: how effective are they?

Does anyone has some sort of home made design they can share? Or perhaps has the original baffles laying around collecting dust? I would rather not having to worry about shortshifting/sandbagging in the section where the noise meters are...

Thanks!

I haven't run at Laguna on a 999 in a decade. But, from what I remember, the db killer alone didn't work. But then again, I ran a big exhaust back then.
