Someone in the SF Bay area has 2 sets of pipes on Craigslist, one IS and one Std. Here's the link
http://sfbay.craigslist.org/eby/mcy/1592360645.htmlIf someone wants them, I may be willing give some assistance. I'd be willing to pick up and drop off along I-80 between Oakland and Reno (out to Winnemucca). If interested in pick up, call five one zero two nine zero 7906. Of course you'll need to contact seller, etc.
The IS pipes sound like a decent deal, not sure of the others.
