I'm going to wait for Ant to answer that question, since he is far more knowledgeable on the subject than I.

The 96+ midpipes don't have pre-cat bungs. The O2 sensor bungs are in the factory manifolds on OBDII cars. The rear O2 sensors sit between the cat and the resonator. (his resonators were deleted). The cats's don't get moved. The area between the cat and the exsisting flang gets cut to move the flanges which meet the new header. Same install as Euroheaders.

Either the header or the Mid-pipe would have to have bungs added for the two primary O2 sensors. (the headers may come with bungs). It looked like the Racelands had bungs installed and he had them capped off with bolts.

OP,

Have you tried to fit an X-brace with the headers mounted up?

Excellent work! Bargain mods are always great to see!
Good question about the x-brace.

Since I have access to a machine shop at school, I may really consider doing this myself. It would be a fun project (besides installing them I'm sure).
Can't wait to see the before and after dynos. Is the power noticeable?
I know noticeable power could also be the headers working in conjunction with your other mods though.

well it took me a week to get it done. a few hours here and there. i also had to send one of my headers out to get the holes made bigger. i didnt get that for two days. and what set me back big time was with the situation of the studs comming out with the nut, i had to remove the corroded nuts from the corroded studs, clean them up....... and reinstall them.

yes you are right..... i pluged up the o2 bungs that are on the headers. they are there, so you can run them on a OBDII car. but then again i dont see the sense in doin this upgrade and still running cats. To me, having cats will go against a header upgrade.

here are befor and after pics of the mid-pipe/headers to give you guys an idea of what went on there.

Shhhhh. Those are "resonators" that were removed

I see you kept the h pipe, etc. Any plans for adding a bigger H or an X pipe down the road?

He was just joking about the "resonators" since it's technically illegal to remove the cats

And I think you thought he was talking about the X brace, but he was asking if you were going to build a X pipe or H pipe to replace the restrictive stock section of the midpipe that looks like an H.

Looks good. Sexy headers.

Not a fan of deleting the cats, but it's your car.
