Ethos Exhaust for tackdays?

I have just bought an RVF400 with an Ethos twin stack full system. Do you guys have any idea on the dB levels of these setups? I have trackday booked at Bedford and it is 101dB. bit concerned I might not pass the noise test.

Cheers.

Most likely louder than 101db, if theres a trackday before the 10th pop along and get it tested

Cheers DM. My other bike is a KTM RC8, so I am stuck between a rock and loud place. Might borrow a dB meter and see which is quietist :)

I still find it pathetic that such things have to be done because morons move next to race tracks and complain about the noise. Er, hello, it's a bloody racetrack!! How about not building a house right next to it...?

Or just dont rev it as hard as they ask you

not once has a noise tester looked at my tacho.

They'll keep an eye on the noise during the day. You can go somewhere on the Goodwood website and see a report of the noise measured there every day, I think. I'd be willing to bet anyone close to or above the limit during a session would be pulled and asked to submit for another test. MSV do two tests, static and ride by, according to their site. Maybe the ride by is simply a case of them having a meter or two around the track at a certain distance away that equates to the static test.... who knows?

Not advocating circumventing trackday rules but if youve already booked something and have no time to get a new system / can to comply

These metal scourers can be bought cheap from aldi / poundland etc.

If you wrap tie some good thin wire to one and then jam it down the exhaust, leaving only a slight bit of wire sticking out near the end-can you can pass the test easily. then with some smal pliers etc pull it out on the sly.

Ive seen many people do this for mot noise tests

Maybe I will just jam a couple of 'nanas up the pipe, Beverly Hills cop stylee. Cheers for the advice guys. I may get a couple of cheap dB killers just to be sure.

I've got a Scorpion can on an otherwise stock system, and it passes MOTs with it fitted. Can't be that loud, I suppose. Never had my collar felt for it, either.

A few years ago at one of the 400GB track gatherings at Cadwell 'Hipringle' came down with his new GSXR track toy - which promptly failed the noise test

Back to the padock and following the suggestion of one of the noise testers to "find something to muffle it a bit for the test", we had a Blue Peter moment with the foil tray from the previous nights disposable BBQ and some tywaps....

Re-tested....passed and given the required "noise tested" sticker.

I seem to recall that despite our best efforts to make sure the Tywraps were secure...the improvised DB killer subsequently eeerm ...fell off just before the first session
