Inspectors here are also supposed to do a visual test but many are not well educated and can’t tell the difference between a cat, resonator and muffler (especially in quick lube stores) so most of them skip the the visual test.
Ok. I was hopeful that's what you were saying.
I'm ready to give it a try, I think.

Next question:
Is this just a simple flash? I have a flash tool that came with the tune I bought from VRTuning. I can swap back and forth easily between the factory tune and the custom tune.
If I can find the ROW tune file, is it that easy? Or must it be programmed to my car / VIN or something?

Or is it deeper than that?
