Decat on 901

[majestic-fries44]

I am checking this 901 Expedition that I am thinking of buying. I noticed that there's an O2 sensor mounted near the cat outlet, it's quite close to the shock, so not sure if a heat shield would even fit now. If I'm planning to run a decat pipe, what kind of tweaks should be made? Anyone else worked into a similar setup?

Since you're planing on doing a decat, then you'll need to get one of those o2 dongles or whatever they're called because they fool the ecu that the sensor is there, whien in reality it's not. Other than that I think you should be fine

This is correct. You might also need a spacer or a tune to stop a check engine light, a regular heat shield might not fit, so heat wrap could be the way to go.

Try checking ECU tuning or sensor tricks to keep things smooth post decat
