fyi: 3" 200 cell metal core cat $95
 

Since it was virtually impossible to find a true Metal Cat branded high flow cat, I started looking for an alternative. I found the Eastern Catalytics high flow cat (79130) with the same specs on the Performance Peddler site. Price was $95 shipped. It's not polished, but should have similar flow. Found other power oriented applications using this unit too.

do you know if they have it in a 2.5in?

No. But I know they exist. The guy on the phone was very professional, worth calling IMO.

I use a 3" Metalcore cat on the Machine and getting a 2.5" on the daily driver. Got it through TurboTim/Shore Motorsports so PM him if you want one. https://www.miataturbo.net/forum/member.php?u=1150

Your's isn't "metal cat" brand. It's either magnaflow or vibrant which at one point were the same thing according to my magnaflow rep. Vibrant changed at one point and now their metal core cats are no longer spun.
