A Full 3″ Mandrel Bent Stainless Steel Solution

The AMS PerformanceHALF Race Downpipe set replaces the lower downpipes and cats on both sides of the VR30DDTT engine. These are catless downpipe sections that allow you to maintain the primary downpipes and cats that come from Nissan.

The AMS Performance VR30DDTT Race Lower Downpipes are the best performing and most durable on the market. During testing our shop Q60 with our full 3″ mandrel bent VR30 Race Lower Downpipes, and Red Alpha Tune, our Engine Calibrators saw gains across the power band in both wheel horsepower and torque! The power came on earlier and the twin turbos 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.

PRECISION CONSTRUCTION FOR UNRIVALED FIT AND FINISH
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 VR30 Race Lower 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. Weight savings are also improved. The AMS Race Lower Downpipes are over 62% lighter than the stock components. AMS’ Engineering Team produced a product that doesn’t just perform better, they made it sound better too.
The VR30DDTT Race Lower Downpipes offer a more pronounced, throaty exhaust note under wide open throttle yet are subtle at idle and partial throttle. It’s a perfectly balanced sound.
