NYNJA manifold/b pipe chamber

[fischer550]

I have an fx1 and have an opportunity to purchase a true fx1 factory pipe chamber. The guy thats gonna sell it to me says I can choose between the factory pipe manifold/headpipe, or a new nynja manifold/headpipe for the same price.

He says that the nynja manifold is ported bigger than the factory pipe one.

I have a stock motor with a high compression head, which combo would you choose?

use the original factory mani and headpipe.you can always bore it yourself if needed.

just make sure you measure the headpipe size
you want the later model 46.5-47mm for 701cc engine
the early ones from factory pipe were 42.5mm
you can always port out the early ones to fit the 701 late size

I think he said fpp one is 47mm nd nynj is 52

Hell I would just go with the NYNJA since its larger.

fpp is a known quality and holds its value contrary to the poor copy also.

Very true, had a friend that got a nynja setup and it was cracked

Nynja headpipe can also have less clearance from the hull, might be enough to cause an issue in an FX1.
