Hi Ian

I tried various ways of quietening down a CRD exhaust but in the end gave up and sold it - they make a good price on eBay wink

Assuming we are talking about the same model of CRD, this is what I found inside mine:

Repacking it didn't make it any quieter sadly so I decided to try restricting the exhaust using the "penny washer" method:

The modification didn't make the exhaust significantly quieter but I gained performance from the increased back pressure wink

Regarding the CRD bashplate, can you post a pic of the flappy front. I might have something to help fix it biggrin
