State emissions

[Kros383SS]

Im assuming even though I have the newer engine in my OBS truck that it still goes by the yr of trk?

If thats the cause I live in an emissions county and it has to go on the rollers for the two speed test.

I guess I have to look into cats.

So do ya'll guys think a stock LQ4 with a tune with pass the sniffer with no cats?

I think it will pass everything but the visual inspection. The Gen3 engines are very clean running.
