It's part of a whole new exhaust setup. Headers, these custom cats, Armytrix cat-back. Everything is stainless, and also ceramic coated (Cerakote). Since the Armytrix set already had two valves (which I also changed out for normally closed ones), I figured these were an extra bonus, for getting more unrestricted flow. On the dyno, my setup makes 379HP with a stage 2 tune. I thought I showed the cats on this forum, as I never seen something similar.
