I bought a Beaudesert 3" stainless about 12 years ago and have no regrets. It followed the original path of the stock exhaust on the Hdj81 and used the stock hangers. It also came with a 3.5' dump pipe which produced lower exhaust temperatures. The owner of Beaudesert arrange the shipping by air and it was less than I thought it would be. It came with the same muffler setup as original and many people have commented on how quiet it is.I looked at - TOYOTA LANDCRUISER 1990-1997 80 Series 4.2L Turbo Diesel Exhaust | Beaudesert Exhaust and also reached out to Whistle 'n' Soot who just said starts at $940 but didn't seem to any pictures or details.
I looked at the eBay stuff which seems to be what a lot of guys are selling and then decided to ask here as plenty seem to be running a 3".
At this stage I am guessing I will just buy some 304 in 3" and make my own as there ain't much to it I was just being lazy .
