H22 SWAP header question

[TheTempest]

Hey,

I had a question about this:

Exhaust:
For the H22A the USDM 93-96 Vtec manifold will bolt right up to the CB7 Exhaust. However the JDM H22A down pipe seems to have larger flange that will not bolt up to the CB7 cat. You can either cut and weld a new flange or the easiest route would be just purchase an aftermarket header for the 93-96 Vtec Prelude.

I'm going to be using the JDM for the extra 10hp. I know other members on the forum have used the DC sports header. Now my question is, what's the difference between the 94VTEC prelude DC Sports header and the OEM header?

I'm confused because I'm just presuming that they bought the same header from DC, though that doesn't make since. The only thing i can think of is that they bought the USDM header for the JDM engine so the mount would line up on the cat.

If that's true, don't you lose some of the horse power from the jdm engine? If not, why does honda ship if with a larger flange?

Just some questions I had, I just got my helms for my accord and i'm making my final preps for the upcomming swap in March. Btw, I live in SA, TX if anyone wants to help (who has previous swap experience )

I would say your best bet with the exhaust problem would be to get an aftermarket header, you can go cheap or really expensive if ya wanted. With the h22 ya get what ya pay for when it comes to a header. You could start off with a megan racing off ebay for cheap and then modify the collector and then get all that welded up and should be a decent and cost effective upgrade
