the cossie one is going to be way way too long, by about 3 feet so it'll be poking out of the front bum[er if you try and fit that
if you use the normal V6 xr one it's got the extra sheilding on it anyway as it runs so close to the exhausts as stadard, so a bit of heat lagging around the otuside will also help with the temps around teh cable
you will also find lagging the exhaust and turbo helps no end as well as giving you a bit less room to play with
