Morning all,
Following my recent thread about some emissions issues etc on my .:R, I am possibly looking at replacing my cats with a milltek hi flow, and also possibly a remap. So I thought...hmmmmm.....add a cat back exhaust on...air filter...pretty much at Stage 2 already.
Anyone know of the gains, benefits etc of Stage 2 upgrades for the .:R?
Comments, pointers, critiscisms etc welcomed :-)
Andy
