Size of Stillen Gen 3 couplers?

BrandonSS · 04-08-2014, 01:49 PM

According to fedex my Stillen delivery showed up today at home. I want to stop at the local speedshop and pick up some blue couplers for my kit.

Does anyone know the sizes I need? Just 4 2.5" couplers?

Thanks in advance!

IIRC,

the pipes are 2.5. Hope that helps, but id take the pipe with you vs. buying them on a guess.

Thanks Riptide - I can always bring them back if they dont fit. I wasnt sure if the coupler between the intake and throttle bodies was a different size like 2.75 reduced to 2.5"

I also need/want to replace the pcv hoses as well, any clue how large/long those are?

Is the stock throttle body on the Z a 2.75" or 3" diameter? I think a reducer is needed for the Z, no?
