HPA Downpipe | MK6 R · 8P A3 | AWD

Maximizing engine performance starts with engine heat management. Turbo charged applications generate extreme amount of surface heat at the turbo charger that radiates directly into the aluminum head reducing the engine ECU’s ability to advance ignition and fueling maps due to detonation. Besides strict global emissions standards resulting in restrictive catalytic converters being installed, oem engineers must factor global restrictions on minimum clearances for front impact crash test results when packaging and designing the factory turbo downpipes. The average OEM 63mm downpipe diameter coupled with a restrictive catalytic converter and varying angles don't allow for ideal flow specifications and result in higher back pressure at the turbo forcing it to work harder and generate excessive heat. HPA’s resulting 3” downpipe is a fabrication assembly designed around functionality and durability and proudly manufactured in Canada. .063 wall T304L stainless mandrel tubing is precision tig
