Not enough back pressure?

BBK has a high rate for rebuild requirements on their regulators, just my .02 cents. Aeromotive sells a good one IMO

As for the AFPRs, i have a aeromotive. Had one about two years ago and the diaphram shrunk up on me, aeromotive claimed to have redesigned them since. Anyway i bought another one and i set it at 39-40 psi with the vacuum line attached. The instuctions say to set it to 48 psi static (with the vacuum line dettached). even with my stock cats back on i noticed an improvement at higher rpms. On another subject anyone have the UPR catted x pipe? just got mine today and installed it. It didnt fit! It pushed my exhaust back to the axle! Any comments.

Just FYI, with an off road pipe, it will smell rich. That's normal with them.
