Question Use of turboxs Dwn Pipe, throw code
I am too install a Turboxs down pipe this pipe eliminates just the one cat from the turbo and still leaves the other cat by the o2 sensor, will this still throw a check engine code?? or not?

Yes a catless downpipe will result in a P0420 catalyst inefficiency CEL. The third cat is downstream of the rear 02 sensor and isn't monitored by the ECU.
