Default Re: Not enough back pressure?

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.
