The air inlet pipe at the bottom of the box has a clamp arrangement at its bottom end. What is this for ? Is there an extension pipe of some sort so air is picked up away from the hot exhaust ?
There is also a small clip on the underside of the box towards the front can anyone tell me what this is for or what it connects to ?
Finally does anyone know what the thread is on the elbow stud - it looks metric ?
Thanks for help.
