Luguna Seca Sound Limits - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Laguna Seca has a 92 DB max sound level.
Any know cat back exhaust systems used there that passed OK, or didn't pass?

It's Laguna Seca!!! And it's 92db and pretty strict. What I and others tend to do is let off at the corners they have dB-readers. I have a straight pipe bike and never have been flagged. It's around 120-130dB and I just let off for a few seconds

Spent all last night reading and the Perrin exhaust sounds like my best choice for performance and quietness. So i ordered it today.

I have the Perrin and hit 89DB at a local Autocross, so you should be set there.

I've got the Perrin 2.5" resonated, definitely a nice sounding exhaust. If you want more volume, you can always add an aftermarket front pipe (I have a catted one), still sounds great with no rasp or drone.

although, i have not db'd my dezod exhaust, i would venture to say that's 92 or less for sure. at cruise and such, it's very tame.

Google images: Laguna Seca exhaust.
You can run loud exhausts there, you just need to add on a track pipe that point the exhaust up and away from all the db meters. they're on the right side of the track.

I thought Laguna is 90,and some times depend the event. That's y I've never been there..... too strict for a track I think
