Exhaust requirements

[Random]

Is a heat shield on the exhaust required for the IVA test? I have wrapped the exhaust down to the silencer, but wondering what to do with that and it's sharp edges.

Do you have the GBS exhaust where the cat and exhaust are in the one piece? If so, that is fine for IVA. If not, read the manual - I don't recall there being any requirement for a heat shield but could be wrong. Also, if it is a very exposed exhaust end and it does get very hot (if you've wrapped it all the way along, that will happen), you'd probably want a heat shield for your own safety.

People will tell you that you need to allow for the sharp edge on the sprung hook (if you have the GBS setup) that holds the exhaust end on the bracket but I didn't do anything and I had no problem (although I may have just been lucky?).

Indeed I need to deal with some sharp edges. Only just started looking for a shield and unsure where to get one from, or how they attach. Would indeed be safer with a shield.

Not needed for IVA my mates passed without one but sharp edges of silencer need protective cover we just used the knock on general rubber covered trim and it was ok, the examiner wasn't happy with studs through body with nyloc nuts and washers to silencer he wanted nuts changed to domed nuts.

my heat shield has 2 big jubilee type clips fastened on inside which slide over silencer an tighten with screwdriver when in required position
