Well Since White Brothers It seems never release the E2 for the 426 or 400 I am left at other choices. After waiting 1 year for this pipe, I am totally disgusted with WB and its attitude on getting this pipe out Anyone using th PC 496 and or the FMF Q or the Yosh with the Tech quiet kit? What are he Pro's Con's based on your experiance? Have they met Sound test 96db? Quality of Pipe? Would you by one again? What does it do to your bikes Power?
