Exhaust Back Pressure Gauge Install

So I did a little looking around and couldn't find what I was looking for.

I got an ISSPRO backpressure gauge with the backpressure install kit, and I'm just curious how you guys are running it on the steed speed manifold with the ports on the bottom.

I have an EGT gauge in the backport, so I'm using the front port for backpressure.

I've read that you want the copper coil to turn upward, so there is less soot build-up in the coil and sensor.

Is that true, or can I just run it down under the manifold to the back of the engine bay?

I think I used the port towards the back, but I can’t remember, and the engines are hot right now, so I’m not checking.
