Check engine light after exhaust install..
I just installed a GT Haus exhaust. 150 mi. Later I get a check engine light. Has anyone run into this before? Car only has 5700 mi on it.

If it's a cat back, you probably have a small leak at the connection pipes.

I had something similar after installing my long tube headers on my new ZL1. I had accidently sliced one of the wires on the wiring harness that extended to the O2 sensor. I would double check all wiring and make sure all connections are tight. Even though you might not have working around that area. I would double check all wiring connections for the O2 sensors.

snall exhaust leak will cause that code...start the car on ramps and feel for a leak at the front connection pipe area where the slip connection is located
