And also u say that the RS Silent has the potential for more power with other mods where as the R1 provides more backpressure...then u say the R1 extra has the potential for more power with other mods once the two pipings are upgraded??? Sorry for the confusion...trying to clear this up in my head. Which one can make more power?

Thank you for clarifying; I apologize for any confusion. It basically boils down to the options you go with. There are three options in terms of pipe designs that can determine the overall flow.
RS-Silent - most potential for more power due to design
R1-Extra-standard piping (dual 50mm) - great option for NA cars due to back pressure
R1-Extra-upgraded piping (60mm) - more potential than the standard R1-Extra for power
I hope this helps.
