Please look at the pics !

Ø45mm inlet with an M8 stud for mounting. It’s the type available at bike shows and autojumbles and also on eBay.

This is in a used condition and ideally needs painting in a matt black as the chrome is past its best.

Just the job for a trials bike. There’s no db killer but it is internally ‘baffled’ with a perforated tube.

Any questions ASK!!
