Thread:

Remove catalyst from Mercruiser 350

I have a 2011 Mercruiser 350 with the catalyst system on it. I am looking for a bit more power and want to upgrade the exhaust system. I am concerned about the catalyst system. I have been looking for information on the best way to handle this, but I cannot find anything specific. Has anybody done this yet? Is there a way to remove the cats without screwing up the system? I would apreciate any suggestions you can offer.

On another forum, this was pointed out to me:

Max Volt Catalyst Eliminator Computer - CP Performance

This is just what I was looking for. Does anybody have any experience with this?

I would leave it alone unless you reflash the ECM parameters.

Why is that?
