    I've searched and not found any real answers.... Will a spacer be all I need if I fit a decat pipe?

    Have you had a remap before hand?

    I'm running the setup you're asking about and it's fine without a map. You'll want a 90 degree O2 spacer as it's a really tight fit, no EML in over 1k miles. Initially (within 10miles of fitting) got a code that the 2nd lambda wasn't heating properly but cleared that and it's not come back. I suspect it was probably just the copper grease causing a blockage which has now burnt off.
