Im going with a begi "s" with an sr20 t25, im looking to get around 200rwhp and ill be using a SS separated gases dp from begi. For the rest of my exhaust i would obviously like to continue 3 inch exit from the DP back. Ill be doing a custom cat back to an already acquired magnflow 3 inch muffler. As for cats im thinking of using a magnaflow cat. This one here seams very reasonably priced, although im unsure if its the right dimensions.

Anyone have any experience with this cat?
Opinions/comments/suggestions. And a test pipe is out of the question due to smog laws.

Fixed that for you.
Grassroots Motorsports just did a test on an n/a miata using various cats and test pipes and found that a decent high flow cat was not noticably different than a test pipe. the stock cat was the suck though.

Im doing the same, i guess i could go with a test pipe and swap it in as needed, but i also like the idea of not polluting the air too. Ide like to be as legal as possible and not get hassled by the local law if they decide to pull me over.

GRM mag just had a miata cat test. Though they tested the smaller 2" and 2.25" pipes. Like deliverator suggested the round "spun cat" with metal substrate beat all the others in flow. It actually outflowed the test pipe near redline by 1 hp. Though that may be due to tuning.
Oh they are more durable in regards to heat and vibration too![big grin](https://www.miataturbo.net/images/smilies/biggrin.gif)
And magnaflow does offer a metal cat which is what they were testing. I'm sure any brand would be fine.
