Power comes in earlier and turbo spool-up is 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. The 4.5″ full mandrel bent downpipe is the best performing and most durable on the market. Power comes in earlier and turbo spool-up is significantly improved. The long gradual transitions within the mandrel bent pipe allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. 

The AMS Engineering team utilized Solidworks (3D software) to blueprint the inlet and outlets to optimize exhaust flow. The AMS MKV Supra Downpipe features heavy gauge stainless steel to retain as much heat in the down pipe as possible. 

The AMS Engineers 3D printed the downpipe to ensure an OEM level of fitment. The threaded O2 sensor bungs allow the use of factory O2 sensor. The AMS downpipe perform better and are not prone to cracking like the alternatives offered by some of the competition. The AMS Engineering Team produced a product that doesn’t just perform better, they made it sound better too.
