F25 N55 X3 Catalytic Delete

Hi All,

I plan on gutting the catalytic or installing a downpipie soon in anticipation of getting the Bootmod3. In the interim without the Bootmod3, aside from it triggering the check engine light, is there anything else I need to worry about?

Will the DME make any changes or reduce power in anyway?

Thanks,

Roy

If that is your daily driver I would highly advise against doing that.

Roy, I would buy both together. I currently have BM3 uninstalled on my x3 because it was in for service. Trans acts a little rough in under medium throttle conditions because it gets confused with the high flow downpipe and the noise that the turbo makes before it spools up is incredibly annoying.

Do it! Unless you need to put stock cat on and or smog in your state. There's literally no drone with stock muffler and smell is subjective too

When I stop seeing diesel trucks, passenger and commercial, stop spewing black smoke out their tailpipes then maybe I'll worry about what's coming out of mine.
