So we don't have true duals? Damn, I always thought we did. Again, what do I know? 
Thanks for the clarification.
I know members on here do a quad setup on their 535s, are there any drawbacks to it? It looks cool, but does the sound come out weaker, for some odd reason or another? Maybe less build up to create the sound? Or is the resonance based on something else?

the stock exhaust is not a true dual exhaust. It has dual piping from the downpipes, switches to single piping in the single muffler, and comes through as a dual tip. The rpi exhaust has dual piping from the downpipes all the way back to the dual mufflers and dual tips.\\
