The band clamp that sits around the silencer is the band clamp that is delivered with the Excell full exhaust.
The small aluminium bracket that sits "in between" the band clamp is also delivered with the Excell full exhaust (this one bolts to the underside of the top of the heat shield when using the standard seat).
The angled aluminium bracket that is attaching the Excell aluminium bracket to the rubber hooped clamps is home made.
The rubber hooped clamps are just standard parts that can be found in most auto parts stores (these are inside diameter 25 mm to clamp around the tubes of the Skinz seat frame).
The block-off plate is not the Skinz plate, as this one is made for the standard header pipe and their shorty silencer. My block-off plate is home made to fit the Excell full exhaust. The piece just in front of the silencer is a "deflector plate" that will stop snow and water to spray up in front of the silencer. The reason this one is needed is because the hole in the block-off plate has to be made quite big just in front of the silencer, in order to not interfere with the silencer springs.
