I abandoned the project for a few reasons:
1. The primaries on the S54 headers are so small that they did not mate up to the stainless M54 flanges that I had bought on ebay. Smaller primaries are...
Well I am trying to move forward on this project and ran into an issue. Just posted on e46f so copying it here in case anyone is considering this...
So I thought I would be able to pull this off...
Just because of the different DME, really. The primary O2 sensors that set your fuel trims will still operate just fine. The M54 stock cats are right up on the block, so the DME is looking for a...
You would definitely have to code out the O2 sensors with the cats being that far from the engine, but I don't see why it wouldn't work. Still have to change out the flanges of course.
@GoGators thank you so much for documenting your journey here. I've been looking for a catted header solution for the M54 and this looks to be the most reasonable solution, despite the headaches...
