So the one on my 2000 XJ is different then and if so in what way? Would it be a different downpipe or something, the reason i ask is i'm looking at building a free'er flowing pipe. Also does anyone know whart these manifolds are like?http://www.ebay.co.uk/itm/140688865677?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_500wt_1034
