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. This very loud aftermarket upgrade is excellent for waking up your Maserati.
