NoVa emissions requirements

[Shadow2]

Just picked up a '13 S6 and already have the itch to mod it. Would like to install a stage 2 tune and downpipes, question is should I go catted or not??? I actually just moved here from MD and know nothing of the emissions testing requirements for VA. Im in Reston if it makes a difference.

Give the folks @ NGP Lorton a call when it comes to passing VA emissions. If you still lived in MD, you could get away with almost anything!

In Virginia for most modern cars they need to pass visual for emissions. E.g. either or they can "see a cat" sometimes this is not possible because of how tight the spaces are in the engine bay, and the other part is not having a CEL or showing that the emissions system is still looking for readyness via obd2. What it really comes down to is if you are positive that you can eliminate the CEL with your downpipes, and that is typically done by using a O2 sensor spacer.

Personally if I am throwing money at chancing not passing emissions I would just get HFC's and call it a day. On my old cars they have typically shown no power reduction, they really just add heat more than anything, which can reflect in higher egt's but hopefully the flow will out weight that.

It all depends on the person doing the inspection. Sometimes they are really anal and try to make a fast buck on the uninformed customer.
