Supertrap

[headsup]

I guess I put this in the wrong section of the forum. Trying again...

Hey guys, Alan Parker just reminded me that my old 1.6 miata was very close to blowing the sound meter at Devens last year and they are dropping the Db level. (yes I still do cones with my kids) It's only a matter of time before I get snagged elsewhere.

Can anyone advise where to pick up a Supertrapp or similar device for a reasonable price?

Thanks
Brian
