What size Would be the best?

[CRXproject]

Im having a problem deciding, what size would i get the most preformance out of my b16A. Im getting the exaust done on monday and i dont know what size pipe should i get?

umm we need to know mods.
i say as a rule of thumb

very build N/A motor/or small build with nitrous 2.5"
turbo or built with Nitrous=3"
small-medium build 2.25"

tell me what ur mods are, and future plans and i can better tell u the size.

2.5 is good for a pretty powerful NA motor for our hondas. Turbo 3inch for us, and higher for others...

2 1/4

2.5", if hes lowly modded now he can always upgrade and not be choked off.

also, on a lightly modded car, 2.5" is more top end, 2 1/4 is more bottem end.

use 2.5 from the header back.

true

I have a 92 hb with a b16a and I went 2.5 but wish I would have gone 2.25 because I have no cat but my friends with a cat has 2.5 and it rocks

2.5 so you don't have to do it again NA
