ayup all, how noisy is a tt with a race can (triumph stainless) at standstill will it be over 105db
if anyone has a decibel meter could you go and see for us even if its the standard can i would find it quite interesting

reason being is i want to do a trackday at oulton park and the noise limit is 105db

any comments greatly recieved

Russ,

There are so many variables in determing the db level. First, different brands of silencers are going to produce different levels; so measuring one competition silencer may not tell you very much. Second, the placement (angle to and distance from) the exhaust will also be iinfluential. Third, the rev level will obviously influence things, as will taking the reading from a standing bike or a bike during a fly by.

105 db seems moderate, and I would think your Triumph can would pass without difficulty. Triumph exhausts to be more mellow than others. Your best bet may be to try a racing bbs and ask those who have to deal with this question on a regular basis.

My nokia 5100 has a DB meter built into it.. Im not sure what other makes had this feature, but it would be good enough to give you a clue.. just have to find someone with one hehe prolly pick one up dirt cheap on ebay

105db is LOUD!

If you are worried then best thing to do is get a DB KILLER so if they say it's too loud on the day you can quieten it down.

Something like this:
Wolf - DB KILLER
or this
Performance Racing Parts - DB KILLER

You can usually find some on ebay too - just do a search against "db killer"

I've done track days at Brands no probs with an open can. Their limit is 105db but they didn't appear to do any test and you're out there with bikes with full race exhausts!!
