I was fairly surprised too when I smelled it. It's not strong, but definitely there sometimes. Maybe it's not from the DP's as I got the lean fault codes pointing to bad injectors or vacuum leak, but I don't recall smelling it with my stock exhaust. It's at the dealership now as I speak, so I'll find out later.
I'm not going to bother with E85, too much hassle.
