I'm possibly looking at replacing the exhaust manifold, downpipe, and shortpipe with a cheap header. I need to find an exhaust leak, which I suspect is in the gaskets on either side of the short pipe between the downpipe and cat, which those parts are going to run $50.
CarID has a Spec-D header for $108, another reason I'm thinking of doing this, at some point I'd like to replace the F22B2 which shouldn't even be in it with a JDM H22.
Although the Spec-D seem to be of dubious quality, and O2 sensor holes not well placed.
Any help to fitment, and recommendations for a decent header in the sub-$200 range, or even closer to $100 would be greatly appreciated.
Thanks!

 

Don't know any other brands of headers, but I can tell you that a f22 header wont fit an h22.

 

Start the car cold, run you hand with a rag around the exhaust and see if you can find the leak.......you could also run a bit of seafoam through the engine (lots of smoke ) and look to see where the smoke is coming out of the exhaust system.
