One set of headers that I was informed would work are a set of Magna 3.0L headers and they apparently bolt right onto the 3g head and don't need any modifications to fit. Although, you would still need the O2 bungs to be welded onto it as well just like the RPW ones would.Thats too bad I'll send them a email to see if they are still around.
Thats good to know that it is not a direct bolt on because I had thought it was. I wouldn't mind obx headers (a few guys IK run those) which also need modification but are almost half price. How would you design your own system might I ask? My local exhaust shops said they don't install headers.
I feel that, always a struggle but hopefully you can find the time. I was actually dealing with a miss fire as well. Every time it rained / snowed the care would trip a miss fire code but ran fine. One time it rained so hard the car actually started and was miss firing at idle for a minute. My mechanic and I diagnosed that when moister gets into the distributor it causes the code and when bad enough can cause a miss fire. After the engine gets hot and the moister evaporates the car works perfect. I have brand new ignition system (ngk plugs, ngk wires, distributor cap, rotor) so it is a flaw with the cars design. Not sure if this helps but thats my experience.
Thanks again for the info!
Now, how easy it would be to find a set is probably not gonna be that easy but it is another avenue if you choose to pursue that as well as they seem to be one of the best headers out there! Or if you can't do that, DNA headers will probably be another option but these need modifications like the OBX to fit properly too as far as I know. Reason I say this is because eventually I will be buying headers for my Eclipse as well and I was looking into this stuff also. Let us know which ones you choose to go with!
