F3 noise level

Hello all

Since I got the F3 beginning 2012 I havnt been for a track day!

The problem I have is that the bike is to noisy for the tracks i live close to. Mostly the track noise limit is 95 or 100db, and the f3 is rated to 106 (according the frame sticker havnt tested myself).

Is there a way to make it quieter so i can pass the 95db limit?

All of you that take your f3 to tracks, how did you do?

Is it only here in europe that the noise limit is lower than the standard bike noise level?

Grateful for answers!

Hi,
I'm in the same situation : you have to buy a racing silencer to pass the noise limits (it's not a joke) I bought a termignoni carbon who sounds 94dB with the killer. By the way, you 'll win some ponnies and loose few kgs!!
Go and see in performance thread the pictures.
Cheers
The D16(ducati motogp street version) is in the same case.Not allowed to run on tracks with the stock exhaust.

If you are confortable with your bike, you are not fast enough ! John Kocinski

We have the same issues here in the UK. Most tracks are 102-105dB. So I'm a bit worried I won't make it out to the track without some serious expense!

As I understand Brands is a bit lenient, but I'm going to see if I can get the bike properly tested before I commit my cash to a TD.

I'd love a new pipe but if I was to spend the money I'd prefer an FM or Zero one, which certainly won't pass the noise limits.

But for the price of a new pipe I can get a cheap Track Bike!

Wildfire, one possible option is to to select the rain map when noise testing, as it delivers a significant bhp cut and a soft and gentle throttle curve, it may well be a bit quieter when you have to test it. Then when waiting in pit lane select sport and off you go.

I done a sound check in rain mode and found it slightly louder. What I have found is that the bike is 4-5 dbs quieter when cold. Dont warm it up before Sound check.

I got this exhaust for trackdays from a forum member. Not the best looking exhaust but it was cheap. With the aid of an db killer and a t-spoon got the sound down to roughly 96 db cold. Gotta get it properly sound checked to see if I can get on at castle coombe. 105db @ 3/4 max revs its gonna be close.

Hi!
We have have big problem here in Sweden also . We use another method I guess.. We have a 95 db "bypass" and the db-tester 10 meters from raceline. With the Termignoni with db-killer it gives around 98db so itīs not easy. Without db-killer it gives around 102-103 db. I have close contact with the factory to see if they can make something more silent, so we just have to wait.

Life is racing

Any recent experience with stock f3 675 on track? I signed up for a track day and am getting a little nervous...

Calabogie motorsports park in Canada, if anyone has any experience that would be great.

Just figured I'd follow up, my bike rated 96db from 10 feet. No issues, there were some pretty beastly rsv4s that were much louder than me so maybe I was lucky or the bike just wasn't warm enough to truly scream.
