FAO Doki

The spamtrap bit is the stuff before and including the N, but it redirects to an account that I don't check anyway. Bit daft and I ought to fix it ;).

Anyway, in response to the sound deadening, I went to my local autofactors and asked for some. Box of ten 50cm x 20cm sheets for £20 (!), stuck a load in the drivers door, none in the passenger door as I was in a hurry to get that one back on. It certainly seems quieter, but that might just be because I stuck the doorcards back on after driving without any for 6 months. The stuff's surprisingly heavy, called Tetra Pad and made by Tetrosyl. Bear in mind that something seriously quiet has thicker glass, tight panel gaps to reduce wind noise and so on as well as a load of wadding type stuff under the carpets. Probably worth sticking £20 quids worth of the stuff to the firewall and seeing if it makes any odds, might be enough to keep the bird quiet ;). The exhaust might be the biggest thing you can alter to make it quieter, and a slight performance loss from a quiet box might be better than loads of extra weight trying to keep out the noise from it.
