Header

[MazdaRider]

Now I got to mx3's yay me
The 4 DOHC
An now the V6 an I was wondering if anyone knows if theirs
A header for the 1.8

[mx3_ryder]

I believe the 2.5L mx6 probe headers and y-pipe will fit.

I installed MX-6/Probe GT OBX Stainless headers when I did my KLZE swap on my 93 MX-3 GS. Pictures below:









You can find them for ~ 300USD +/- shipping

They fit well, but will require your cat to push back ~ 6" and the pipe from the back of the cat to the pipe going into the muffler will need to be shortened... or you can just get a custom exhaust welded in and dump the stock exhaust setup... in the attached photos I had my modified pipe on, since then I have replaced the cat back with a custom system, all welded in....

Hope this helps,
Tim

So the KLZE header will fit the 1.8??
But isn't the KLZE a bigger motor??

They will fit... you might lose some low end power by going with oversize tubing for the 1.8 vs 2.5 L displacements... might help your top end HP numbers slightly... assuming you go with a high flow cat, and say 2.25" exhaust tubing to a free flowing muffler...

What about these headers? http://www.ebay.com/itm/PROBE-MX6-V6-19 ... f9&vxp=mtr

No idea about the generic ebay headers. usually the saying, you get what you pay for applies to auto parts...

Will actualy be 3" pipe with a high flow cat

[clunet]

You must be talking about forced induction if you are talking 3" pipe. 2.5" is overkill for a 1.8 - 2.5 NA liter engine...

I bet they're both made in China

At present, they're all about the same from what I have seen. Unless you get your hands on an older set of headers, the gains basically vary from set to set, all branding aside.

Buy what you can afford; If you don't mind the sound being a little more annoying, the PaceSetters are worth looking into.
