which b pipe is the best ?

[iptamenos]

hi

factorypipe produces two types of exhaust b pipes

one named as limited for stock engines

and one named mod for modified engines

My questions is

in a good engine with a lot of stuff in it like 760cc with pump gas ported and ada head etc

which pipe you would buy
i ask this because i think that mod pipe has smaller chamber from the limited pipe and i know that as bigger as possible the chamber is you gain more hp ?:smashfreakB:

The Limited pipe works well for most freestyle engine applications.

The shorter length Mod chamber results in a slight increase in power and rpm but shifts the power band higher and the torque curve is not as wide.

The longer Limited chamber has slightly less horsepower and rpm, though it raises the torque slightly with a broader range.

Use the search feature in the upper right corner and type in Mod & Limited because this is a very common subject. :Banane37:
