VW Golf R HPA Motorsports Downpipe

The fabricators at HPA set their sights on the R20 downpipe to optimize backpressure and allow the calibrators the headroom to maximize both power and torque.   The resulting 3” downpipe is a fabrication assembly designed around functionality and durability. .063wall T304 stainless mandrel tubing is precision tig welded for an ultra clean look. Our CNC formed hanger and laser cut flanges mate this assembly to the chassis and will withstand the thermal conditions the turbo will generate. Our flex couplings feature an internal stainless steel interlock liner that facilitates smooth flow of high temperature exhaust gases.   HPA downpipes come standard with our 100C high flow cats. The same cats used on all HPA twin turbo vehicles.   Golf R specific Downpipe   Removed the Factory Cat directly off the turbo for substantial increase in flow.
