Can u guys tell me how to modify the Stock h22 header to work on my h2b?

 

Some guys are heating it with a torch and bending it downward. The other option would be going to someone fab capable and actually cutting the "a" pipe, or secondary section of the mani if you prefer that language.

I just did a setup like this for a guy and it turned out pretty well. I ended up jig'ing it in order to build an H2B specific header.

so its okay to cut and modify the oem pipe? is aluminum ok to weld to the oem pipe? what about that torch technique how long do u gotta cook it up?

 

Aluminum...ahhh...no.

Yeah, the H22 OEM headers have a steel (i.e. non cast) second section. You can cut it, and just use 16g exhaust tubing to mod it, then MIG or TIG it. You'll have to remove the heat shield, and do it at the bend by just removing some.

If you go the torch method, just heat it up red hot and put some torque on it...it'll bend.

 

cool but i thought the exhaust tubing was aluminum or maybe aluminized.

 

Another question i have the stock h22a upper part of the header, can i use a stock b series lower part i mean downpipe part and mod that so i dont have to try and locate a h22 downpipe?

No, not aluminum...aluminized. It's steel that has been treated with an aluminum-silicon alloy that gives the steel and anti corrosive characteristic. When welded the coating burns away. If you clean the pipes really well on a wire wheel it'll weld descent.

No...ain't gonna work without modding it. Locate the lower part, or just have a fabber fab the lower section altogether. The flange wouldn't be difficult to make, as it uses o-rings to seal, so it'd be a straight forward deal with a flex section, etc. If you were local to me I'd fab it right up for you no problem.

 

mani if u jiged it can u make me a down pipe that will work on my h2b? if so how much?

u said to modify the oem header by cutting at the bend right? what bend are u refering to? the curve as it goes down the oil pan or when it starts to bend up towards the steering rack?
