Toyota Supra GR MK5 3.0 HKS Sports Catalyst Downpipe

This HKS downpipe designed for the Toyota Supra GR MK5 3.0 fits without any modifications, from the turbo all the way to the catback, on the B58 engines, to replaces the stock 600-cell catalytic converters with much more efficient 150-cell sports catalyst versions. Made from high-quality SUS304 stainless steel with a 85mm diameter, this HKS downpipe engineered to reduce back pressure by 40%, offers a power gain of 10hp and 11Nm on a stock engine.
