AMS PERFORMANCE TOYOTA GR SUPRA STREET DOWNPIPE W/ GESI CATALYTIC CONVERTER

Our 4.5" full mandrel bent downpipe stands out as the top performer in the market, boasting exceptional durability. With this downpipe, power delivery occurs earlier, and turbo spool-up sees a significant enhancement. The elongated, gradual transitions within the mandrel bent structure enable exhaust gases to maintain velocity, preventing the buildup of back pressure within the system. Our superior engineering prowess has allowed us to design a product that surpasses others in performance.

Moreover, our catalyst features a newly formulated substrate with a specific wash tailored to meet the latest vehicle emissions requirements. It's not an off-the-shelf catalytic converter; rather, it's engineered to meet and exceed contemporary standards, ensuring optimal performance and compliance.

• Significantly Lower Back Pressure Means the Potential for More Power
