I got the pipe on ebay for $175 its for a 87 - 92 Lt 250. Is there a special upper mount for the Expansion chamber. any info would help where does it work good according to the bolt adjuster on the pipe

 

Most pipes go up far enough to use the stock pipe mount that is on your frame. The LRD pipe uses it too but has an adaptor which is basically a piece of metal that has two bolt holes and just moves the mounting location about 2 inches down. You kinda need it or your pipe will be a litlle loose . The flange bolts and the silencer bolt keeps it pretty secure but id definately try to get the adaptor before too long. This adaptor is in addition to the two bolts that hold together the 2 halves of the pipe. The two pipe adjusting bolts can be replaced easily though at any hardware store. my pipe cost over 300 so you got a decent deal.
