| New Exhaust Diesel Smell in Cab So I had an exhaust put on this weekend. Now when sitting at a light with the HVAC in "outside air" mode I can smell diesel exhaust. Is it possible something is not tight enough, ie the band clamp, or is it just because I no longer have the fresh clean DPF exhaust anymore and the HVAC is sucking up the fumes? Anyone with a straight pipe exhaust get this at all? I tried to put the heat to recirculate, but it just flashes and goes back to outside air...

| They will all do it. My last 4 diesel trucks all did it.

| Mine does it to. After I put an aftermarket down pipe it's not as bad.

| Nothing wrong with it... just wanted to make sure all was tight and I wasn't damaging something because it was leaking where it shouldn't be.
