Calibrated elbows on DI

[Mark93]

I’m wondering if anyone knows which calibrated elbow I should use on my 2002 GTX DI. The old exhaust pipe was heavily corroded at the copper gasket joint and leaking so I replaced it with one I got from eBay which was salvaged from a 2000 RX DI. The only thing that’s confusing me is the calibrated elbow on the outlet of the tuned pipe to the air compressor are different. The one from my original pipe was a “16” and the one that came with the new pipe was “18”. The hose connection is quite a lot different so much so I would need a smaller hose.

My question is are the connection calibrated by the flow of water through the tuned pipe or the model of ski? As I’m not sure which one to use?

Normally you can down load the parts manual for free online. It will give you the part number and you can then order it.

Use the old one that came off your ski on the new pipe.

I have checked the parts manual but only gives a part number but not the size of the fitting.
