Exhaust Measurements

[n8zg]

Anybody have an RV-7 or -9 with an Aerospace Welding 4-into-1 exhaust?
I need a few measurements, please...

I have a 7 with a AWI 4 into 1, not flying yet but what measurements do you need?

Thanks Don -

What's the diameter of the collector/tailpipe where it intersects the vertical plane of the firewall, and what is the gap between the bottom firewall flange and the pipe at the same location?

The tailpipe diameter is 2.5", the gap is 1" at the requested location.
