Lamborghini Aventador SVJ Sport Catalytic Converters


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.

High-flowing, direct bolt-on replacements for the bulky & restrictive factory catalytic converters provide increased exhaust flow, sound, and power while complying with most emissions regulations.
