ETD Racing 2.5" 300 cell high-flow catalytic converter for 1994-1997 1.8L Miata

Was purchased new, back in 2008. Was used on the track car until we changed to test pipe in 2009: http://slickauto.net/?q=node/54

Has some light scratches on the bottom from loading and unloading the car over a trailer ramp. No dents. No rust. Catalyst material intact, very low miles usage. 2.5" ID (see photo below). Direct bolt on for 94-97 Miatas. I wouldn't know about passing smog with this, but if you need a durable, high-flow cat for a supercharged or turbocharged Miata for track-use, then this one is great for that purpose.

$60, local pick-up in Rowland Heights, CA. $75 shipped to USA.

Interested if :
- not sold
- length is ok for my '90 1.6

Here is some info found on the net regarding length :
There are three different cats fitted to the Mk1,
1.6 or 1.8 upto 1994. This cat is 370mm in length.
1.6 or 1.8 from 1994 to 1996. This cat is 440mm in length.
1.6 or 1.8 1996/8. This cat is 475mm in length.

How long is yours ? :)fab::woolery:)

I'm not sure how these lengths were measured, but both inlet and outlet flanges are at very steep angles. This means that without a reference diagram on exactly how these measurements are to be taken, there is no way for me to properly replicate the measurement.

According to Mr. Goodwin's website, the 475mm only applies to certain UK models: http://www.good-win-racing.com/Mazda-Performance-Part/11-1033BG.html

Since this high-flow cat was made in the USA, for 94-97 1.8L USA cars, then we can assume that this is equivalent to a 440mm spec cat.

This cat will not bolt-on to your 90-93. Aside from length differences, the show-stopper for you is that, due to differences in the factory manifold and factory down-pipe in the 94-97 vs. 90-93, the flanges for the 94-97 are welded on at different orientations vs. the 90-93. The only way to fit this 94-97 high-flow cat onto a 90-93 would be by cutting off your original cat, cutting off the flanges (and some portion of the pipes) of the high-flow cat, and welding the high-flow cat to the gap left behind by your original cat. Quick job for a muffler shop, but definitely not bolt-on.

Thanks for the answer !
I need to study what I need for my Begi 1.6 kit then, sounds a bit more complicated then I thought.

edit :
If not sold what will you be your price with P&P to Euroland ? I have a couple of stainless steel welders in my network, may be able to fix the part to fit :D
