Does anyone run an 850 turbo with the SuperSprint cat back exhaust that has a rear muffler but not a center silencer /resonator?
SuperSprint offers two systems - the only difference being that one has the center resonator and the other doesn't.
My 850 is a US model - with original cat and downtube.
I am wondering how much louder the system without the center resonator will be.
Can anyone offer any insight on this? Why does SS make a system without the resonator - perhaps is it for racing?
