G' day everyone newby here to the site. having a look through the forums and its very well laid out. good job. heaps of info. I drive a 2004 d22 tray back navara. looking at a few improvements such as extra 70ltr diesel tank. under tray 80ltr water tank with pump. set of cooper st tyres not sure on size yet. and a 2 inch lift. more into the touring camping scene than hard out rock climbing 4x4 trips. but still do the trails etc. so an exhaust from superior engineering will help and i just found a web site from the uk that does a diesel chip called chip express i was thinking of trying. anyways cheers for reading see you around. Aaron.
