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.

Cat Bypass Pipes eliminate the factory catalytic converters - offering a very aggressive tone and burbles and crackles on downshifts and during decel. Tubing diameter is increased from the factory 60mm 2.375" round O.D. size to 2.75" 70MM size for much better exhaust flow and high speed scavenging.
