just a little ask has anyone fitted the above as opposed to the standard downpipe and if they have will it need any extra fittings brackets etc?
It's fitted into the existing pipe. You cut a section out and add the silencer, needing two clamps that byou should buy with the silencer.
As far as I know, no extra brackets. A couple of people have fitted them, I have mine still to do. Maybe add it to my Nano list.
