I'm about to finish the H22 swap for the ride but about to do the Header/CAT/Exhaust set. Right now I got a stock H22 Header, H22 downpipe, No CAT, and the F22 Apexi WS2 exhaust. In my search I'm going to need to get a H22 Catalytic converter. I'm thinking about buying a direct fit CAT for the h22 prelude which is 13 5/8 O.A.L but I'm not sure if I'm still going to need to modifiy any length on the exhaust, H22 CAT, header or downpipe. Id hate to cut something on the exhaust as it is pretty much new and less than 5k miles. Does anyone else have any other suggestions?? Can anyone confirm this and what kind of setup they have on their swaps?

Thank you,
J

 

I think if it's different, it's only a couple inches different. for the 90-93 h22 swaps, we just use the old cat conv with the old exhaust. hope this helps.
