Is it possible 2 change my stock single exhaust for dual exhaust? And if so how exactly?

 

It's a lot of work on the sedan, the EVAP canister needs to be relocated and the bumper would need to be trimmed. Look under the rear and you'll see what I mean.

The pipes would need to be custom bent by a local muffler shop, I don't believe there are ANY bolt-on kits.

There are however dual exhaust options for the sedan but they all exit at the same location in the bumper.
