Hey everyone. I have a 2013 Cruze Eco 6M, with 110k miles, bone stock. Lately, I've started smelling exhaust while sitting at traffic lights, in traffic, or otherwise stopped with the engine running. When going down the highway, I don't smell it. I've looked under the hood, taken the heat shield off over the turbo, the clamp to the downpipe seems tight, the 3 bolt flange after the pre-cat seems tight. I can't seem to find where this exhaust is leaking from. I don't hear any leaks, the car sounds the same as it always has. Not sure if anyone has any ideas or has encountered this issue before. Thanks.
