I am planning on getting a downpipe on my mk7 GTI (one that will guarantee no CEL like the neuspeed downpipe). I know that this will pass emissions if an OBDII test is performed, but not so sure about a sniff test. Does anyone living in northern virginia know if OBDII or sniff tests are generally used in emissions testing? Also if you know a place that only uses OBDII tests, can you point it out to me? thanks!
