I have a 2010 softail custom with a SE 103 street stage 4 kit (SE259E cams), running V&H staggered long shots, looking for better over all torque, ( low to mid torque range) Looking at either V&H big radius 2-1 or V&H pro pipe. Which one would be better.  Any suggestions for sites for good prices. 

you may be able to adjust the noise levels easier on the pro pipe

Hey dv8, look up eastern performance of m& m cycles, their prices are good, thinking about looking at the 2 into 1 big radius myself.

check out Kellys Rubber on OZ  Ebay around 779.00 delivered plus some great tyre deals as well

Ordered V&H Pro Pipe chrome, looking at changing SE259E cams out for T man 625 for the torque to come on earlier
