I understand why you think itll throw a code-- i can promise you I never rec'd a check engine light from a vent to atmosphere BOV! But regardless how do you compare an at most $200.00 modification to a potentially $2000+ modification-? OP you can get a brand new BOV and flange for 100 - 150 and have a aluminum welder put the flange on your ic pipes for less than 50.00!! Good luck buddy
