A New Generation Of "Clubman" Style Box Pipe  Has arrived............. The Avanti Ex-Box
 
This standard Ex-Box has had prototypes on the road since September 2018, how they have been  performing can be seen in the September 2017 issue of Scootering but have been refined since then with more bottom end and mid-range torque, giving a much more smoother torque curve. Noise is VERY acceptable They have the ability to pull higher gearing than most other "Clubman" type exhaust systems.

The Ex-Box is in three parts:-
Stub Manifold ( standard, RT, TS1, RB or Quattrini - please choose from the drop-down menu)
Stainless Steel Header Pipe ( “U” Tube) Standard / TS1 or RB / Quattrini / RT
Main box (exhaust body) with adjustable crankcase bracket
