Dave, yeah axis. And I was thinking same thing... 02 is up stream so cat wouldnt effect that.
I had it made and fitted by Windsor exhaust shop. They are local with a good rep.
First thing I checked was 02 plug, and checked it was tight. Double check wiring tomorrow.
Scotty, sucks they are not obd2 compatable. What tool do I need to scan it?
How do I do a ecu reset? Is it as simple as the skylines and just disconnect the battery?
Thanks for your input guys.
