Description

The Red Alpha 3" Full mandrel bent downpipes are the best performing and most durable on the market. During testing our shop Q60 with our Red Alpha Full Downpipes, and Red Alpha Tune, our Engine Calibrators saw 20 horsepower gains over our lower downpipes and no CEL's! 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. 

Our Red Alpha Full Downpipes also feature motorsport grade, high quality, high flow GESI catalytic converters rated to over 800 horsepower!  The durability of our catalytic converters is second to none and light years ahead of the budget options found on other downpipes. We were able to design a superior product because of our superior engineering.

First in Class Durability and Performance From Proper Engineering

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.


An Unmistakable Alpha Exhaust Note

The Q60 and Q50 Red Alpha Downpipes offer a more pronounced, throaty exhaust note under wide open throttle yet are subtle at idle and while cruising. It’s a perfectly balanced sound.
