I've searched already,

I finished the last of a swap in my brothers 92' si, got the longblock motor from Hmotors, it came with just the exhaust manifold(upper half).

So I need to know how I can make the exhaust work until he buys a real H22 header and cat.

Please help, this is the only thing keeping it from driving

 

umm you cant interchange any of the parts. you need all h22 parts. good luck thats whats got my jdm h22 swaped lude parked in the driveway...waiting on exhaust parts.

 

really?

I've heard on another board that if you drilled the 3 holes to fit the h22 mani that you could us the H23 DP

but i've also read that its either too long or short and that you have to extend it...

 

ttt

 

just get a different flange for the header-->cat connection. You'd have to be a complete idiot to buy and entire new exhaust just because one flange didn't fit. Take it to your local muffler shop and they'll do it for cheap.

 

lol well im an idiot then. i ordered a cheap pos ebay header so i can finish my exhaust. and my local shops were going to be around the price of the cheap header. to ahve the correct flange made and welded on. i didnt wanna just cut and weld it.

i'm going to try this...thanks

 

any other input

 

let me know how much your local shops are going to charge you for putting a new collector on the downpipe. I just skipped all that and got pos ebay headers for the time being until good ol' tax return.

 

You can just duct tape the exhaust together

lol just have the **** welded....or you can drill it out to fit....

 

Just get a custom exhaust piping made for you application. Its the best way to go. buy magnaflow 2.5" cat and a muffler of your choice with at 2.5" inlet and you will bet set

 

he was refering to the collector from the cat to downpipe not the muffler. and i had inadequate tools to drill through that collector i tried

 

i dont see why the downpipe for the h23 is any different from the down pipe on the h22. i know the manifolds are different, but try using ur downpipe from h23. if that doesnt work, then i have an odd ball, cuz thats what i did!

 

the h22a downpipe has a different collector then the h23. itsa bigger.

the h23 downpipe doesnt bolt up to the h22a mani.

so with those 2 statements you cannot use your h23 downpipe. the flanges at the cat will line up but it wont match at the mani.

this is without rigging anything to work. maybe you can modify/drill new holes and it could work , but i am referring to as is.

you used the H22 manifold and the H23 and it bolted right in to both the mani and cat with no modification?

 

the h23 downpipe does not bolt up correctly to the h22 mani. prove me wrong if it does. pics...
