I am getting an exhaust smell that will occasionally come into the cabin from the vents, and I can also smell it whenever my windows are rolled down....does it have a leak? My dad said the only thing he could see was a possibly bad gasket in the middle of the exhaust pipe, where it connects to the midpipe....am I correct on this...anyways, is there any way to tell if that is where the leak is coming from? My dad said the exhaust manifolds were tight...
