Sniff Test
 

I'm up for emissions at the MD MVA and was wondering if anyone has or known somone to fail a "sniff test".

What I mean is that I have a turbo kit, with a ptuning exhaust. I have no code, but when you stand by the thing while it's running it's pretty obvious that I'm not stock. I'm concerned that although I don't have a code, they will smell my exhaust and proceed to a visual inspection (which I would fail).

Does this happen or no?

Well I passed without a problem.
