I wrapped the headers and the down pipe on my 2011 Supersports after advice to maintain heat in the Cat for the MOT.
I t worked..I would normaly have to drive it hard to get the Cat up to temperature and immediatley put it on the emmisions tester.
After fitment Mot passed easily..so no more MOT anxiety !!
It is normal for moisture to burn off on first start after fitment.
I used 58' of 2" wrap.
I recommend using correct stainless clips and not Jubilee clips.
