For any questions please PM or email:  Online@AutoTalent.com Description: 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.  This Muffler Bypass was a custom creation for a customer, who was so fond of it we decided to offer it to the rest of our lovely customers.

Our design process started with 3D scanning the entire exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we settled on using a one piece mandrel bent over axle pipe that goes straight into the free flowing part of the OEM PSE exhaust and a secondary pipe TIG welded to the main section to make a Y configuration to utilize the quiet side of the PSE exhaust when the valves are closed.
