Dave Platt T120 Exhausts

From what I can see in the add they look very expensive. You can buy a pair of slash cuts from about £100.

 

Have a look through here, there's hundreds of styles to choose from. Personally I wouldn't put slash cut end cans on a Bonny as they never - as far as I know - came with them.

I put a set of reverse cone cans on my T100 and they sounded lovely.

They won't be labelled up as specifically for T120 as these are universal end cans. Select the style you like, select the diameter adaptor you need, then install them. No re-mapping required.
