HJS HDPE motorsport catalysts

Designed specifically for Volkswagen models

are after air fuel ratios have been compensated via software for the exhaust upgrade

This allows exhaust gases to more efficiently exit the factory mufflers - increasing velocity and smoothing out sound resulting in a solid increase in power and exhaust volume

HJS EMITEC catalytic converters are 100% Guaranteed to make more power than any Illegal cat-bypass pipes even on Turbocharged engines with aftermarket high performance turbos

Replacing the stock H pipe for our perfect geometry, laminar flow X Pipe, enriches the tone, as well as raising the pitch, and producing a fuller, more aggressive sound to the exhaust note. THE SPECIFICS Catalysts Available in a choice of 100 or 200 cell high flow sports cats. Materials Available in premium grade Inconel 625
