A Full 3″ Mandrel Bent Stainless Steel piping for the ultimate in flow and durability.

The AMS Performance FULL Street Downpipe set replaces the upper and lower downpipes and cats on both sides of the VR30DDTT engine. These are the downpipes to be used for maximum performance benefits during competition and record chasing while operating under off-road use.

AMS Performance VR30DDTT Race 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.

This product is designed for installation on a race-only vehicle, defined as a vehicle that is used exclusively for competition and that cannot be licensed or registered for use on the public roads and highways within the United States. This product is not available for sale on emissions-controlled vehicles within the United States without a completed AMS Race Waiver form. International users outside of the United States should act in accordance with their local laws and regulations.
AMS is first and foremost an engineering company. The AMS Engineering team utilized Solidworks (3D software) to blueprint the inlet and outlets to optimize exhaust flow. The AMS Race Full Downpipes feature heavy gauge stainless steel to retain as much heat in the down pipe as possible. Our Engineers 3D printed the downpipes to ensure an OEM level of fitment. Our threaded O2 sensor bungs allow the use of factory O2 sensor. Our downpipes perform better and are not prone to cracking like the alternatives offered by some of the competition. AMS’ Engineering Team produced a product that doesn’t just perform better, they made it sound better too.
