Fabspeed use HJS 200 cell catalysts which are tri-metallic. HJS cores are produced by Emitec, a Tier 1 supplier to almost every European automobile manufacturer, and completed by HJS in house to exact specs. HJS produces everything from catalysts for extreme racing use, FIA approved, to Euro 6 compliant direct replacement catalytic converters. We take pride in using HJS catalysts and we're the leader in utilization and sales in the US and second largest in the world! It's hard for me to compare to Hyper-Flow, as they don't provide too much explicit information about the origins and performance of their catalysts.
