The increase in engine power begins with the thermal management of the engine. Turbocharger applications generate extreme surface heat on the turbocharger, which is radiated directly into the aluminum head and can therefore lead to heat build-up and increased exhaust gas temperatures. The goal is to reduce the heat on the mounting surface of the turbocharger on the aluminum head. When the equilibrium of heat removal is reached, the applicators can create an increase in performance, which ensures that the exhaust gas temperature and the exhaust gas back pressure are not too high and the output can be sensibly increased. Heat is an enemy of performance, and even with original software, the vehicle will benefit from the fact that the exhaust gases can be dissipated faster and better.

The average downpipe diameter of OEM 63 mm in combination with a restrictive catalytic converter and different angles does not allow ideal flow specifications and leads to a higher back pressure at the turbo, which forces it to work harder and generate excessive heat.

The 76mm downpipe from HPA is a manufacturing assembly that is designed for functionality and durability and is manufactured in Canada. Investment casting 304 stainless steel exhaust flanges and 1.6mm wall thickness T304L stainless steel pipe are precision TIG welded and argon purged for an ultra-clean look from the outside and a perfect clean weld from the inside.

S6 / S7 downpipes have high flow 300-cell metal catalysts, as with all HPA twin-turbo high-performance vehicles.
