I am in need of an exhaust header for an ej22 that is light weight. O.E.M is to heavy for my application...would really like some direction with this. thanks in advance...btw the turbo is now removed.

Most of the WRX/STi stuff is similar. The STi uses the same up-pipe (same part number even). There are lots of aftermarket options for them that aren't cast iron like the stock peices. There are even equal length options, single peice 4-2-1 style, etc, etc.

 

Ask what folks have used over on legacycentral.org. That's the place for EJ22T talk.

yea, exhaust flange location and dimensions are the same for all dual-port EJ engines.

 

some of the newer cars use a different oil pan to clear the headers, so you might run into that. but the oil pan is interchangeable too.....so it might be worth swapping to an STi pan (make sure you use a reinforced pickup though!! the stock STi ones are prone to cracking).

 

 

but since you don't really need it to be smashed under the engine (no turbo), I'd look for something for a 2.5 N/A (like an RS). there are a few options, Borla makes a header that makes for a great sound, and shifts your powerband down lower a bit (better low end torque, but at a sacrifice in scavenging so not quite as much peak hp). There are a couple companies that make equal-length headers for them, with the opposite effect: less rumble, little less low-end torque, more peak hp.

Thank You for all the great info!

 

Hopefully I will post a pic with the EJ22 in the unit when complete!

in the unit huh? what's this going into?
