I'm sure this is on here but I wasn't ale to find it... or didn't look hard enough... Either way, I have CFR's inbound, FP 3 and SE heavy breather.... I know you lose a little low end torque with the CFRs, but not much from what I hear.... But in terms of headers... is there really much a difference between the V&H Power Duals or Dresser Duals? Thanks in advance!
