I have a 991 Turbo, and have a BBi race exhaust and BMC filter, and COBB AP with PDK flash with Stage 1 93 octane.
I saw you added a Y-pipe and plenum to yours after your nods similar to the mods ive made, and am curious if you could feel a strong difference.
I don't want to purchase until getting some feedback from somebody like you with firsthand experience.
I'm thinking of going to Design by Sam for his Stage 2 custom tune, but it might make sense to add the Y-pipe and plenum first.
What do you think of them?
Thanks in advance,
Steve Northrup
