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...

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

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.
