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
Kline Innovation Ferrari PORTOFINO cat pipe set Heat Shield Option BMW-420i-425i-430i-2023 HJS HDPE motorsport catalystsTHE SOUND Replacing the stock catalyst for high flow 100cpsi HJS sports catalysts, we were able to open the sound significantly. 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
