IS your EGR functioning correctly? If there is a leak it could be venting exhaust into the engine bay which is getting pushed into the cabin.

Could be a leak anywhere on the manifold or where your exhaust bolts up. You'd definitely hear a leak like that though so I'd probably guess EGR. Anything further under the car than that and at 80mph you wouldn't be getting it in the cabin.

 

I have the EGR block off plate, and no cats, and the exhaust system bolted up nice and tight, and I get the same smell coming inside the car. It could be a worn hatch seal, tail lamp seal, or just be sucked back in from a low pressure (or high pressure, cen't remember which) area behind the car.

exhaust leak, same problem on my car. i can stick my 2 hand and plug my exhaust tip. i canhear hissing noise coming out of my leak.

 

double check your blockoff plate. it really shouldn't be entering your car at 80mph...
