The AMS Engineering team utilized Solidworks© (3D software) to blueprint the inlet and outlets with smooth features and geometry to optimize exhaust flow. They then 3D printed the down pipe to ensure an OEM level of fitment before casting the very first article! The AMS VW MKVII Golf R Downpipe upgrade, unlike some of the competition, also comes complete with a laser cut form fitted heat shield to protect critical components that sit close to the downpipe. This includes the ABS module and it’s plastic heat shielding. The AMS Golf R downpipes feature 4mm thick cast stainless steel upper section that retains as much heat as possible keeping it out of the engine bay. By casting these downpipes in robust 304 stainless steel we were not limited by the design constraints of hand fabricated construction.
The AMS MK7 Golf R Downpipe features an extremely wide mouth that matches the exact shape and size of the turbine outlet. This increases overall turbine efficiency and performance due to a larger pressure ratio between exhaust manifold and downpipe. The long gradual transition within the downpipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. The AMS system includes a fully widened 3″ upper downpipe, midpipe, and subtle transition pipe to adapt to your factory exhaust components.
Another unique benefit is our motorsports grade catalytic converter. These GESI brand 300 cell count Ultra High Output (UHO) units provide virtually no disruption in flow providing emissions control with no notable loss in horsepower. For durability these converters feature a staked in design to hold the catalyst cores firmly in place. Many competitors offer a low quality catalytic converter option to keep the cost low and their profits high. These units often fail due to poor construction and inferior materials. When you choose an AMS Performance VW MK7 Golf R Downpipe, you will remain worry-free for years to come.
