Introducing the A90 Toyota Supra Mandrel Bent Stainless Steel Full Downpipe
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 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.
Significantly Lower Back Pressure Means the Potential for More Power
Exhaust Gas Can More Easily Flow Across the Turbine Wheel
Throaty Exhaust Note Under Wide Open Throttle
CAD Engineered for Maximum Exhaust Flow with Unrivaled Fit and Finish
304 Stainless Steel 4.5” Design Reduces to a 3.5” Flex Section, Maximizing Volume and Flow
Turbine Flange Offers a Smooth Transition from the Turbine Outlet
3.15” (80mm) Outlet Allows You to Run Either Stock or Aftermarket Catback Systems
Complete Bolt on Means No Cutting - Bolts to the Factory Location
O2 Sensors in OEM Locations. No Jumpers Needed
Mandrel Bent Tubing for the Best Flow
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 Red Alpha 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.
