MQB (AWD) 2.0T Downpipe

HPA street downpipes come standard with our 300C high flow cats. The same cats used on all HPA twin turbo vehicles.

* Required Fields



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.

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 ecu’s 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 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. .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 300C high flow cats while the new MQB GTI and Golf R come standard with our 300 cell metal cat, the same quality of cats used on all HPA twin turbo high performance vehicles.

Amazing QualityReview by Christopher
Once I opened the box this DP came in I could see the quailty....Sounds Amazing as well.. Nice performance jump with a Stage 2 tune :) (Posted on 6/28/2018)
Better than OEMReview by J Epp
OEM fitment, VW Technician installed. Instantly felt the gains and much better response. Paired with a tune its the best way to go. Don't waste your time on an inferior product to just pull it out and fix - replace your OEM with equal or better! (Posted on 6/28/2018)
Great Sound, No CELReview by AJLawyer
I had this downpipe installed on my 2016 Golf R in January 2017, and it has been a great success. The stock exhaust sounds more aggressive, and it has never thrown a CEL. (Posted on 6/28/2018)
Realy good productReview by Mathieu
The downpipe fit perfectly and sounds good (Posted on 6/15/2018)
Excellent quality Review by Steven
I had this installed with the cat at their shop. This product is top notch and has increased performance and better sound. (Posted on 6/14/2018)
Amazing DownnpipeReview by Ray
Quality and price can not be matched for this downpipe. Blown away when I had the chance to unpackage it (Posted on 6/14/2018)
