Currently in the process of choosing a new exhaust syst. for my 2006 d22 3.0l TD that already has a tunit chip fitted. im struggling to make a decision between Beaudesert 2 3/4" mild steel syst to my door for $1080 and a system from roo systems, which is 409 stainless 3 inch system with no cat, just one muffler (would have thought this would be fairly loud, but the bloke there doesnt think so) for $1495 to my door. roo systems also offered to retune my tunit chip to suit the new exhaust syst. the bloke from roo systems was very helpful and seemed to have a fairly good knowledge of the 3l navaras. my question is, has anyone had a system from roo system? what was there experience. i've also noticed very little people on here with a stainless syst? at this price i cant really say no
