Thanks for the help!

The SDS 550 installation I'm finishing up will have the sensor about 10" from the tailpipe outlet, only place I could mount it. it is a dual three into one with big (Canada eh) heat muffs & ball joints, Ross figures it should be fine.

My last SDS 360 installation (Vetterman crossover) had the sensor in about the same relative location, it works acceptably but the reading flutters a bit.

We usually recommend the sensor be around 12 inches from atmosphere and at least 12 inches from the port, if that's possible. We want to avoid very high temps on the sensor and air contamination due to flow reversion between exhaust pulses.
