R35 GT-R
Hi, I searched but couldn't get a good reply on this topic:
I just reflashed my 2014 GTR with the AP Stage 2+ tune. It has Cobb 3" intakes, AMS Downpipes, an AAM midpipe.
I also put my rear O2s on the end of minicat spacers, to really make sure I didn't run into catalytic converter related...
