Going to try over here to see if I get a better response. I want to upgrade my exhaust system. Is there really any difference between the Rush True Duals and the Rush Premium True Duals. Is the extra money worth the premiums.

 

Im looking at rush aswell.
premium or high output have a crossover so are like a powertune duals and deliver better low end power.
we have a tuner here trained by the Doc who swears by the power gains he gets with rush headpipes. won't even tune with V &H .
Im going with the rush HO $444. at cycleplicity
