[Healeys] FW: Side exhaust idea

[Peter Dzwig]

Simon,

very interesting.

Some years ago I had a custom system made for my 100/6 by a company called
Bell(?) or Bell's in Swindon. I think that the cost may have been £200 or
thereabouts. It was very effective with piping similar to yours but they
recessed the box a bit more than yours looks like it is (although they may have
used a more flattened section box) and I think that the pipes were cut closer to
the side to avoid risk of burning.

Worked very well took me down from 108dB+ to something more road legal.
