Removed the left side exhaust system and deburred the inside where I drilled for the EGT probes. Afterwards, I rechecked the probes for fit and reinstalled the left side exhaust...this time with the proper hardware for a final install. Once it was installed, I added the EGT probes and torqued the band straps. The CHT probes were installed next. When all this work was done, I reinstalled the lower cowling and tweaked the muffler just a tad for a final fit.
