Fairfax county emissions and midpipes
Hey all,
Quick question. I’m looking to get a milltek midline which, I believe, replaces the secondary cats. Is this going to cause issues with safety/emissions inspections in ffx coubty (Herndon)? Thanks! |

I would say "maybe". i should not show as a flag in the OBD, but the tailpipe test may fail without the secondary cats doing their thing.

I’m in the same boat, I’m planning on getting it emissions tested at my shop that does everything. Figured it would pass but maybe fail visual inspection and hopefully they don’t look that closely
