I am new to my '85 FJ60. I am carrying on the struggle to pass Colorado emissions. BZ has rebuilt my air pump. I am replacing all the vacuum tubing. I am cleaning and testing the various components per the emissions manual. In addition to summer gas mix and some E-85 to help, seems the best next step is to use ABV to route air from the pump into the exhaust down pipe. Unfortunately PO removed stock exhaust downpipe so I have no ability to connect air pump output to the exhaust down pipe. On Ebay I located an OEM exhaust down pipe being sold by BTB products (ebay tag is landcruiserparts) out of Henderson, NV. Does anyone on MUD have experience with them? Positive or Negative - please let me know. Or do you have other sources you would recommend for this exhaust down pipe? Thanks.
