Default Bore Size, Fitment Help (jdm To Uk)
Hi all,
If you got a B16 with JDM 2.5" Bore manifold is there any way to connect it to a OEM 2.25" system, with a 2.25" decat?..

You can use either a 2.5" decat, or a custom 2.5" high-flow cat (which is what I'd recommend).

It won't be too large because the actual flange that bolts to the exhaust is the same overall size and same bolt pattern. The difference is only in the size of the inner bore itself.

you can weld a 2.5'' flange onto whatever exhaust you're using
