I think you shouldn't add duals since it's "only" a V6. Cheaters!! lol

 

Yeah, if you ever plan on adding dual exhaust, then the cutout is no good unless you want to replace the bumper cover. If ford had done the 99-04 mustang like the one pictured I would have been so pissed at having to replace the bumper cover to add dual exhaust.

 

Even then, it would still be a lot nicer-looking than the bumper covers ricers add to their cars. To have two gaping holes in the bumper and only one exhaust tip, you definitely fit the definition of ricer.
