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.

Get these! You won't regret it!
These are my go-to winter shoes! They are waterproof- I love them bc they don't look like your typical "rainboots"! Stylish- I get compliments everytime I wear them! Comfortable- first time I wore them they were tight through the middle of my foot, but after two wears I had them nice and broke in, now my most comfortable shoes!

So nice but not a good fit on my foot
I love these boots so much, they’re exactly what I wanted. Unfortunately, they are too big in the heel and flop, while too tight in the toe. I know the toe would stretch with wear, but can’t deal with a floppy heel, they pulled my socks down off my feet. I do have narrow feet. Too bad, I’m so disappointed! They seem well made and would go with everything. Comfortable, too, if they fit right.

Best boots I have ever purchased
I do appraisal work so I was looking for something cute/professional yet durable and rugged for when I work outside in all types of weather. Found it! So comfortable, so cute, and waterproof. I wear them most days for both office work and inspection work. I range between 8.5-9 and I got a 9 and they fit great both with thin socks or thick socks. I very highly recommend.

Perfect for travel... very comfortable!
These things are amazing! I bought these a couple weeks before a trip to Italy and had planned on doing a lot of walking in them. I only got to wear them a couple times before we went on our trip, but no blisters, even during LOTS of walking in them on the trip! They wore in super quickly while still keeping their durability. My feet stay dry even in lots of rain. The photos show the wear on them after a few months, including a couple weeks of travel, and weeks of wear around town. My only complaint is that there is a tiny something (a little knot of thread with glue? not sure...) that is at the top of the opening of the boot, and it rubs the back of my ankle and makes a sore. That isn't enough to make me not wear them though. There's a photo that shows this. As you can see it's super tiny, and probably not even a flaw, it just hits my ankle *just* right so that it rubs.
