Now that I know where to go, the last bit of info I require before I make a purchase is at what temp would be considered redline for the exhaust temp? Trying to decide between color coded gauges....
Going from memory here, which might be an issue. Wait for confirmation.
The greatest danger of the heat and high temps is, of course, to the engine. Aluminum starts to melt at ~1300°F. The pistons are at risk then. Therefore my absolute max is 1250°F. I try not to ever go even that high. Others have claimed to run a sustained temp higher than 1300°F, but they are few and far between. I wouldn't do it.
The other factor, which you have not yet asked about, is placement of the probe. Since the danger point is the engine cylinder(s), you would want to measure as close as possible to the engine. The further you go from the heat source the cooler the exhaust gasses will be. You must compensate for that fact. Some people drill and tap the exhaust manifold between cylinders 6 and 8. You can't get any closer than that. Personally I have my pyrometer probe poking into the exhaust downpipe just below the manifold flange on the driver's side.
Before you drill for the probe, be sure to ask here about a specific location.
