R3 noise level trouble at Laguna Seca?

Hello! First post here. Browsed for a while.

Anyway,

I've searched high and low and can't seem to be able to find any direct info about the R3 with an exhaust running at Laguna Seca. Has anyone run one? Was it too loud? Did you get flagged? Slip-on? Full system?

I don't have the stock exhaust, so that's not an option.

I do have one of the Akro clone full systems with a baffle installed. It's not really all that loud, especially compared to my Buell or ZX6, which both have slip-ons, but I'm not sure if it would pass their 90db sound tests.

Any info and experiences would be great.

They have a db limit, and it's 90db?

I'd honestly be surprised if anyone with a non-stock exhaust can make that. I don't know all the options for the R3, but IIRC the Graves full systems run at about 92db (5k rpm) with the insert installed, and the Akrapovic carbon and older ss model runs at 99db according to their websites. Both are under 90db at idle though, so I don't know what the requirement at Laguna would be measured from.

This is my signature. Woo.

You bet your ass they do. Try looking up Laguna Seca pipes, they can be rather entertaining. But Laguna requires you to be at or under 90dB when you pass the checkpoint at speed (which is on the right side of the track)

Did find this interesting blurb on fun track dayz's website about Laguna's strict policy. Some stock bikes don't even pass which is pretty wild but be prepared to make modifications if needed.

So, no one on this forum has run at Laguna with a non stock pipe on their R3? Well, that's surprising, but at least we know what we're dealing with now... 😅

Yeah, clearly I had no idea. You might be the first, or at least the first on here. If you give it a go, please report what you find! Also, good luck.
