I used an ISSPRO pyro for my setup.  Installed the probe in the O2 sensor hole on a dual downpipe gas manifold.  Just drill out
the metric threads and tapped for 1/4" NPT to make the probe threads.  Nice clean install.  You can also weld on a threaded bung
(might work on the downpipe) with the ISSPRO kit, or some kits use clamped on probes.
