High Performance sport headers improve exhaust flow and sports car sound; Sport Headers include 200-cell HJS Sport Catalytic Converters.    

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.

Dyno Graph

Dyno chart provided by a customer:

"This is not a same-day comparison, but the difference is large. The headers led to a 14hp and 18ft/lb bump at peak, with the TQ peak coming in 350 rpm earlier, but the really remarkable thing is the difference in midrange - at 4,000rpm the difference is almost 50 ft/lb. This explains the car's turning into a city-street weapon!"
