Direct replacement for the restrictive OEM headers, offering improved power and throttle response throughout the RPM range.
HJS German imported catalytic converters are made from some of the highest grade material 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.
