if the exhaust gases are going down a separate pipe then they would fail emissions due to there being no cat. if you added the cat then there would be no point as the cat would increase the back pressure.
in newer VAG cars 1.8t and 2.0TFSI if a BOV is fitted the cars should overfuel as they are looking for the pressurised air being flowed back into the intake from the DV
