fitted a CM tip today, well i watched as my mate struggled, got the old one out fine. and all this having to jack the NS up and bring the tip out from the bottom is nonsense, managed to get it out from the top of the bay and put the old one in, had to trim an inch off the new one at the turbo end, and getting it to fit on the turbo and doing up the jubilee clip was a massive ball ache, took probably an hour or so just to do the tip.
