Sport Catalytic Converters
High-flow sport catalytic converters for the Acura NSX Type S / TT (2017-2022), replacing the 4 small, restrictive OEM ceramic units with HJS German-imported 200-cell tri-metallic converters that flow 93% of a straight pipe. Built with CNC machined billet stainless steel and 321 stainless steel flex bellows, with provisions for the factory primary and secondary catalyst heat shielding so the OEM shields still fit. Fabspeed states this produces no catalyst-related check engine light while still delivering an aggressive sports car sound with prominent turbo spool. Saves 21 lbs (9 kg) over the stock 4-cat setup. Ships with all hardware and gaskets needed for installation.
