Re: O/r h pipe tune?
It will depend on where you live. Some states use sniffers, some states use visual inspections, and some states have no laws about it. Personally, I am from West Virginia and I have become very good friends with a guy who does my inspection. And for me, as long as the CEL isnt on he says that everything must be there and working...wink wink. However, i have been lucky and my CEL never came on after swapping to longtubes and my prochamber.
