    And the numbers are in

    Just wanted to share the numbers. I had a very bad feeling that my cats (replaced in 2013) were gone as the test numbers exceeded the allowed maximum.

    So after 2 new Walker cats (part number 81132), 3 bottles of catalytic/O2 cleaner, the SMOG test results are amazing. So clean!

    Also cleaned and re-gapped spark plugs.
    Changed fresh oil and oil filter
    Cleaned air filters

    Do you by any chance have a picture of the new cats installed? With the dual inlets and single exits, I'm having a tough time imagining how they fit.

    Sorry, I didn't think of taking pictures. The installation will require cutting and welding. The dual inlet pipes facing the motor side and the single inlets face towards the rear and mated to the silencers.
    It will require a trip to your local muffler shop.
