Descriptions:
Increase horsepower, torque, and sports car sound by replacing the factory catalytic converters with high-flowing 200-cell HJS cats.
Why We Choose HJS Catalytic Converters:
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. If you’d like to learn more, watch our video about HJS catalytic converters.
SOUND:
Replacing the factory catalytic converters with high flowing cats and our cast X-Pipe will provide a mild increase in volume while also revealing a more defined exhaust note.
Power:
We saw curve gains as much as 15 whp with this system thanks to much better flowing 200 cell cats and the knife edged cast X-Pipe.
