Attention: Important information regarding the purchase of this downpipe.

Despite the ECE version, approximately 2 out of 10 vehicles may experience an error message from the differential pressure sensors. We only recommend this downpipe for customers who…

who want to have a software adjustment made or want to work with our OBD OPF error deleter.

Due to the excellent design of our cast parts, it is possible that, despite the ECE catalytic converter and OPF, the pressure sensor threshold may be undercut with our downpipe.

(Which clearly demonstrates how much better our downpipe is.)
