exhuast manifolds

[BluAccord]

hey guys just wondering if u can put an xhuast manifold from a f22a4 and put it on a 91 f22a1? if so does the year and model matter i have an ebay header, after reading on here how others had to bend the a/c pipe and add washers so they wont come in contact with eachother, i figured it would be alot easier to just replace the X manifold and down piping. any advice would be greatly appreciated.

You don't have to bend anything. I didn't

It's a perfect fit since the F22A4 is the same as the F22A1 except for the Exhaust manifold.

You will have to use the a4 down pipe also. The a1 exhaust manifold is a 4-1 while the a4 is a 4-2-1.

you would have to swap over the a4 o2 sensor right? Since the a1 is on the manifold and I think the a4's on the down pipe

[Gettin_faster91]

The o2's are the same. You can unwrap the the wire harness and there is enough wire to reroute it or just extend the wires either way.

Expect about a 5hp gain over the A1 exhaust manifold.
