A Full 3″ Mandrel Bent Stainless Steel Solution with GESI Cats.
The AMS Performance FULL Street Downpipe set replaces the upper and lower downpipes and cats on both sides of the VR30DDTT engine. These are equipped with GESI EPA approved catalytic converters for higher HP aftermarket applications. These are the downpipes our RZ34 Nissan Z shop car runs to add power, maintain emissions, and eliminate bad exhaust drone.
AMS Performance VR30DDTT Street Full Downpipes are the best performing and most durable full 3″ mandrel bent units on the market. During testing our shop Q60 with our VR30 Full Downpipes, and Red Alpha Tune, our Engine Calibrators saw 20 horsepower gains over our VR30 Race Lower Downpipes! The power came on earlier and the twin turbo’s spool-up was significantly improved. The long gradual transitions within the mandrel bent pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. We were able to design a superior product because of our superior engineering.
