Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.
The High performance free-flowing Valvetronic Supersport X-Pipe replaces the heavy and restrictive factory rear mufflers and catalytic converters for improved power and sound. It also gives you the ability to change the exhaust note at the push of a button with our Valvetronic system just like PSE. Available in a Street (Sport Cats) or Race (Cat-Bypass) configuration depending on your application to maximize flow and performance. And includes quad Polished Stainless Steel or quad Satin Black Tips to give your 997.2 Turbo the aggressive and finished look that it deserves.
