If you could by it would you if you were looking for a new system.
Say 3.5 or 4" downpipe into a 4" Y'ed to dual side-by-side 3.5"
Just like the 08's

Duals add more exit volume (ummm...4*4=8) but they also add turbulence by not separating the exhaust pulses uniformly. The turbo kinda chops it up, but not enough.
