Wrap is good Dave..I used 58' of 2 " wrap on my Supersports as a guide.
When I fitted the Librands manifold on my 4/4 I needed to undo the engine mounts and lift the engine with trolley jack to facilitate.
Why are you messing about with expensive add-ons ?...just get a hooligan Supersports with all the good stuff fitted and become one of the elite 60 owners !!!
