HIGH PERFORMANCE TURBO DOWNPIPES BY HPA
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 100C 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.

Great for High Mileage vehicles
Size: 12 fl. oz. (Pack of 1)
Added into my 2014 Dodge Grand Caravan with 100k miles before a family trip and eliminated knock, slow starts and improved our gas mileage by about 10% I think! super easy to add to the oil and very happy with results.

Great assortment of clips—fits well and saves a trip to the dealer
Color: 40pcs
Picked up this 40-piece set to replace missing/broken push-type retainers on my bumper/fender liner area. The assortment is a solid value—having extras on hand is way cheaper than buying a few at a time locally. The clips I used snapped in securely and held the panel tight without rattles.
Tip: match the old clip’s size before installing (hole diameter + stem length). I tested a couple first to confirm fit and then finished the job. For basic trim/under-cover repairs, this is an easy, cost-effective kit to keep in the garage.

OEM Quality
Color: 40pcs
These fit perfectly! They are easy to install and very durable! I have no doubt that they are holding everything in place. They are also very easy to remove and do not break during removal, which is great.

They’re okay
Color: 40pcs
These fender clips are just okay. They fit reasonably well and did the job for a quick fix, but the quality isn’t the best. Some of them felt a bit flimsy, and a few broke during installation.
If you’re in a pinch and need a temporary or budget-friendly option, these will work. Just don’t expect OEM-level durability. Decent for the price, but not great.
