Loud exhaust

[ilovespeed]

I have a Caterham Seven and have recently fitted an exhaust which has no silencing and is virtually a pipe coming straight out of the manifold with no cat to go through. Although it is good fun, it is obviously very loud. I am considering doing some trackdays in it but I know many tracks enforce noise restrictions and I am sure my car will exceed them. I am therefore asking if anyone knows of any device e.g. a temporary muffler that I could stuff up the tail pipe, to quieten it down temporarily. Also I’m sure my neighbours will be getting quite annoyed soon!

Thanks for any help in advance,

Geoff
