Message	after doing your DP's? Stock turbos with stock DP's measured 11-12psi right at the bend between the DP's and the midpipes. After the 3" divorced DP install, that backpressure was measured at 0psi. Understandably there must be some backpressure, but the needle didn't move off of 0. That's why we get such better response, coupled with the divorcing of the wastegate gasses for about 7" (The GP divorced downpipes 'meet up' about 3" or so after the split). I'm sure your 3" pipes rock, but it took a custom design to be able to FIT the 3" pipes with the divorced wastegate. The DP is 3" and the divorced pipe is about 1". You can see how that is hard to fit.. :) Nissan Z-cars - the best cars ever built... Go Turbo, or go home Bigger Downpipes = Bigger Man (and faster Z!) Scott Performance in Santa Clara Rocks!
