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.

The NSX is now the Monster it should have been from the factory. Sounds Insanely good and has gotten VERY VERY fast. Scary fast to be honest. I have never seen an exhaust and downpipe do this much to the power of a car...
