Header options
« on: June 12, 2016, 11:45:40 am »
Hey guys, I am looking opinions on headers. I really do not wish to fabricate headers for my Mazdaspeed swap so that I can keep costs down. However the only headers I can seem to find are a shit design 3-1 shorty headers. I am really hoping I can find a better design with longer tubes that hugs the block as much as possible.

If not, does anyone know what the best ebay headers are? I was thinking of either DC Sports, OBX, or Megan (if they even make them). Anyone know which brand sits closest to the block.

well with the swap going into a miata, youre stuck using only the top portion of the header. you'll have to make your own downpipe. all of those headers will be pretty much the same. best bet is custom.

Firstly, thanks for your swift reply, and the information I was afraid of, suspected.

Secondly, |
I will have to see what the Exhaust shop's quote is on building me a set of headers for a j35, but if it involves taking the engine to them to do it then that is absolutley out of the question. I will just have to grab a set of cheaper headers and cut the downpipe portion up and have it rewelded, or more likely just run duals. I figured at least one company would have long tube headers with a nice smooth collector.

P.S. why does this forum have annoying captchas on every single post you make, might have more users without that feature, and I can't seem to find many j-series forums, I thought hondas had all the forums and and aftermarket vendors. I think my Mazdaspeed in specific has better support on the net and that was limited to about 5000-6000 vehicles made for 2 years. And a smattering of international versions similar in spec.

no captcha problem here.  forums kind of died out with facebook groups.

as i said you can make some zoomie headers, which are basically a pipe from each port to open atmosphere, or do that into a 6-2-1 setup.

Thanks, That sounds like a good idea, but at the time it is way beyond my fabrication ability. I don't even own a welder. I need to get one. But it is such a large investment for a tool I only need for exhaust work. I dunno I may end up having to do it. Main thing I am trying to avoid is more and more costs. I was hoping to do this swap a lot cheaper than the LFX swap. The more I dig, the more it seems I may end up needing to buy a lot more stuff than I anticipated.

There's two people I would consider in your situation. The first is LoveFab which is a company that specializes in fabbing j-series exhaust components  (high cost) but have accepted one-off jobs from me and do phenomenal work. The other is one that also accepted one-off request from me but never performed the work due to me changing my mind. If you can find the user "donsbusbox" on ebay, message him and talk to him about making a custom set of headers for ya. Hopefully one of these two sources take you somewhere. Good luck.
