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 ECUs 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.

Each HPA downpipe application is designed around emissions compliance requirements, thermal radiation/contact surface clearances and engine ecu software framework. The calibrators drive the hardware demands to ensure that the dimensions and catalytic converter requirements are calibrated within the spectrum of the ecus capabilities. The goal is to reduce the heat at the mounting surface of the turbocharger to the aluminum head. When the balance of heat reduction has been realized, the calibrators can create a fuel and ignition mapping that will ensure that the tailpipe gases are clean and the boost levels can be raised. Heat is the enemy of HP and even your stock mapping will benefit form a more fluid design of exhaust gas discharge.

The average OEM 63mm downpipe diameter coupled with a restrictive catalytic converter and varying angles dont 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. State of the art 3D printed Inconel 625 exhaust flanges withstand the thermal conditions the dual turbos will generate. .063wall T304L stainless mandrel tubing is precision tig welded and Argon back purged for an ultra clean look on the exterior and a perfect clean weld on the interior.

S6/S7 downpipes come standard with our 300 cell metal cat, the same quality of cats used on all HPA twin turbo high performance vehicles.
