+1 with btbossman with the exhaust system gaining hp and sounding like an beast. I also have the catless downpipes but the O2 sensor extension cables do not get rid of the check engine light, just allows you to secure the O2 sensor in factory clip location. Only solution to remove check engine light is a full ecu tune which we all are waiting on.
