For the absolute best-flowing catalysts, look for a manufacturer named "Carsound". These guys are a bit hard to find, but they have proven over and over again (on flowbenches, dyno runs and emissions sniffers) to be the absolute highest flowing catalytic converters while still being fully within OEM emissions requirements.

They too are universal. They might be a few more dollars, but you won't find a better one on the market.
