Primary Sport Catalytic Converter Downpipes
Sport catalytic converter downpipes for the Alfa Romeo Giulia Quadrifoglio (Type 952), replacing the factory catalytic converters with HJS German-imported, Euro 6 certified 200-cell high-density cats that flow 92% of a straight pipe. CNC-machined billet stainless steel inlet flanges pair with CNC mandrel-bent tubing, and the downpipes work with any rear cat-back exhaust, stock or aftermarket. Fabspeed states these produce no catalyst-related check engine light while still opening up more sports car sound and power across the rev range. At 12.8 lbs (6 kg) versus the stock cats' 17 lbs (7.5 kg), they also save roughly 4 lbs (1.5 kg).
