Sports Cat and VA Emissions

[notJCW]

I'm looking to put a sports cat in my 2018 F56 S. Of course the vendors all say the downpipes are for off-road use only. Does anyone have experience with emissions on a sports cat? Will it pass in VA?

 

Thanks so much!

I ran into the same issue with my Jeep Wrangler TJ when I added the turbo kit - FOR OFFROAD USE ONLY - means it WILL NOT pass emissions.  Change the registration to a county in VA south of Prince William county, emissions not required.

realistically the answer it, It depends. Is the downpipe you are looking at a cat deleted one or does it have a free flow cat? Have you changed the exhaust system and modified the second cat from OEM?

 

1) if it changes the emissions enough to trip a code, automatic fail at an inspection station. Clearing the code before driving will result in a no test due to the ecu "ratting you out". You will have to drive about 100 miles to reset. 

 

2) If it removes the downpipe cat, then by the law it fails, but that requires the inspector to know the car hasa second cat, and checks to see if it is there. So depending on the inspector or day it could pass or fail. 

 

Now if someone was you pass through a rapidpass mobile test, they would be able to go to the website and for a small convenience fee pay for their emission test if they passed (I have never seen a failed one), and there would be no physical inspection.

 

Where might these tester be? https://rapidpassvirginia.com/VaPublic/Locations

This is helpful. I think my plan here is ultimately to do a sports cat (not a full decat) and a Borla axle-back exhaust.

 

Specifically, looking at: https://www.ecstuning.com/b-milltek-sport-parts/downpipe-with-high-flow-catalytic-converter-oem-exhaust-fitment/ssxm429~mll/

 

I would do a Stage 2 tune through Dinan at the same time, so the coding shouldn't be a problem. Would that pass, do you think?

Sorry to hijack, but I am also wondering about emissions testing and replacing my exhaust. The one I have in mind is: https://nm-eng.com/collections/mini-f60-countryman-s-2-0t/products/nm-eng-downpipe-back-exhaust-system-nm308844
