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.

  1. Excellent Headers! 5 Star Review

    Posted by on 24th Mar 2017

    For the money, these are the best catted headers for the 991 GT3 chassis on the market. There are so many long-tube options on the market- it was nearly impossible to find a set of well-engineered catted headers for my car.

    Being a daily driver, there was no other choice. These headers are amazing. Very well-engineered, and with the right tools I was able to install them in my garage without any issues. Car is certainly a louder, pulls harder, and has no CEL or emissions issues.

    Would recommend these to anybody who needs to keep their catalytic converters but wants to get rid of the bulky factory cats/headers!
