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.
Meet the strictest of emissions standards while freeing up power with an HJS 300-cell catalyst downpipe.
This downpipe is produced by HJS themselves as a solution to meet the strict requirements of Euro 6 compliance. As a master distributor of HJS catalysts, we're happy to import from Germany and supply this downpipe. Availability and lead time may vary depending on production volume.
