Noise Limits

[lateconvert]

Pardon if this is an oft-asked question, but how can you find out if your car will pass the noise limit test, other of course, than booking a place and turning up in blissful ignorance to find that it fails on the day?
(TVR Chimaera 500, standard exhaust).

I went along to a local sprint, & got mine tested there, all I need to do now is lose 10-15Db

Yours should be fine for any 98db days (which are about the lowest limit).
I would guess it will be 95 to 97db on a standard exhaust.

www.bookatrack.com hire a noise meter out. £9 covers the hire and P&P both ways

[getcarter]

also... mate of mine used his 500 with stadard exhaust at a 98db day - can't see any problems.

Thanks guys, very useful and reassuring input.

If you think the car is marginal, you could try a SuperTrap clamp-on unit (assuming it will ft to your tailpipe/s), which I believe can be quite effective.

You can add or remove discs to squeeze you under the limit with the least increase in back pressure. Then it's easy to remove after the event.
