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. .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. 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 EA888 Gen 1 and 2 street downpipes come standard with our 100C high flow cats used on all HPA twin turbo high performance vehicles.

The company known as Highway Performance Autostyling (HPA), started back in 1991. HPA specializes in creating aftermarket performance parts for Volkswagen and Audi.They have created numerous builds that won prestigious car shows and won at the racetrack as well. Today, they have become synonymous with performance tuning and have been sought after by Volkswagen and Audi enthusiasts worldwide.
HPA houses a 10,000 square feet facility at Langley, BC, Canada. It has a fully functioning workshop complete with multiple service bays, CNC machines, a fabrication shop, and their very own Dyno machine. With a state-of-the-art facility at their disposal, it's not surprising that the company creates some of the best aftermarket upgrades available in the market today.
The company has been actively participating in various motorsport events. They have recently participated in the Pirelli World Challenge that allowed them to run their cars in different tracks around the world. Through this, they were able to gather vital information on how they can further improve their parts which they later on applied to their products.
If you want to improve your Volkswagen from a grocery getter to a weekend or full-blown track car, then HPA is the brand that can help you. With over 30 years of experience in building fast Volkswagens and Audi, they are a company that definitely knows what would work in your car.
