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 Water Bottle!
Color: Off Road, Size: 30 Ounces
I was looking for an insulated water bottle that would actually fit in a standard cup holder. I decided to try the Owala FreeSip Sway Insulated Stainless Steel Water Bottle. Upon receiving it, I noticed that it felt solid in my hand. The mechanism worked very smoothly with a simple button press opening the lid. Once open, you can choose to either use the included straw or tip the bottle and drink from the chug spout. In addition to it fitting in my cup holder, I needed it to be leak proof. This bottle is leak proof, and the spout can be locked by engaging a lock in the back. The rugged flip handle is also a convenient way to carry the Owala when it's not in the water bottle holder on my backpack. I hand wash the body of the bottle, but the top disassembles easily and can go right in the dishwasher when I want a deep cleaning. The bottle has a wide opening, so it is very easy to clean the inside. This has quickly become my favorite water bottle due to its ease of cleaning, good insulation, ability to fit in my cup holder, solid construction and materials, and the option of using the straw or chug spout. I have the 30 ounce bottle, but I am going to be picking up a 40 ouncer also. You won't regret purchasing one! I have used the bottle for a couple of weeks now, and here are my observations: It has gone on two camping trips, and it has proven to be durable. I have placed the Owala on its side on my passenger seat (just to test it...it fits perfectly in my car's cup holder!). It did not leak a single drop on a long road trip. On my camping trip, the water in the bottle was still ice cold the next morning, so it keeps cold beverages very cold!

The Perfect Bottle
Color: Dreamy Field, Size: 40 Ounces
I do not leave reviews, but I had to for this. This is the PERFECT water bottle. It has a handle, it's leak-proof, with a lock, so you don't have to worry when your baby decides to play with the bottle and tips it over -- there won't be a spill! Straw and sip option are perfect and I love that the straw is inside the cup so I don't have to worry about my kids hurting themselves when they drink from the cup. 40 oz is a great size, holds a lot of water but tapered bottom perfectly fits in the cup holder. So easy to use, my 4 year old has no issues. Cleaning takes 3 minutes. I recommend to absolutely everyone.

Great quality, beautiful colors!
Color: Black Cherry, Size: 30 Ounces, Color: Black Cherry, Size: 30 Ounces
I love my Owala! The colors are beautiful. It's easy to wash out and clean. I like the lock function. There's been a couple of times that I've put it in my purse without locking it and the button accidentally pressed open and spilled. So the lock fuction definitely comes in handy! It's easy to carry around with the handle. It doesn't feel overly big/bulky. It fits in my van cup holder just fine. My toddlers are able to drink from it using the straw function without spilling and making a mess. If I put a lot of ice in it, it usually still has ice the next day. It stays cold for quite some time. The overall quality is great! I'm pretty rough on it and it has minimal scratches so far. I definitely plan on buying more colors in this size!

Amazing, but gigantic. Gave to my partner.
Color: Summer Sweetness, Size: 40 Ounces
5 stars because I got this bottle on sale for the same price as the 30oz, the colors are *gorgeous* and every bit as vibrant as the image shows (which I'm seeing is not typical across the board for owala) and it is indeed just a fabulous, strong water bottle. Easy to drink from the built-in straw, a joy to carry, and fits in every cup holder so far. I've already adapted better hydrating habits compared to using my old daily Nalgene. However, I am 5'5 and wanted a bottle to carry around frequently for work. This thing is like as big as my thigh bone lol! I should have gone to a local Target or Academy to compare the 30oz vs the 40oz bottle because the size difference is significant. If you consider the added weight for a full 40oz, I set myself up for failure in terms of my needs for this bottle. My 6'2" boyfriend who loves colors and works outside all day was happy to adopt this one for me however, and I ended up purchasing a 30oz elsewhere in equally fun colors. We have both had success having ice last a full workday. His keeps cold in the car and mine usually has a good bit of ice still after 3 refills and constant use. So far so good on no-spills, and I really appreciate the lock mechanism as I work around delicate artwork all day. It would be nice if the cups were machine washable alongside the gaskets, lid, and straw-- but alas, it's easy enough to clean in the sink and probably wouldn't fit in a top rack anyway. Each bottle comes wrapped with beautifully thorough care and use instructions as well-- take the time to read it all! Overall, I would recommend this cup 10/10. Cold water all day and a built in straw have changed my daily water intake by and large-- so if you're looking to better your hydration habits, look no further and don't overstep your needs like I did if you work around available water spouts all day... The 30oz is enough.

💯 stars - Best water bottle on the market!
Color: Off Road, Size: 30 Ounces
Lots of tumblr love for this Owala bottle... It's pretty much perfect! I ordered this brand after getting my grandson a kids Owala cup that has proven to be basically indestructible and that's saying something because a 2.5 year old will put something through it's paces. That cup is over a year old now and still going strong. Visually - it's lovely, the color is exactly as pictured but this thing isn't just a looker. She delivers in every way. The tumbler isn't round toward the top, it has these straight edges which makes it easier to grip. the handle is just high enough to hold it w/out being uncomfortable or knocking my knuckles on the spout or top of the bottle. the lock lever behind the spout is nothing short of genius (As any of us know that have 'thought' we closed out tumbler only to have it leak on our computer inside out backpack...) (<-- I'm not the only one, right?) The 'swig or sip' lid is probably my favorite feature. Generally I've preferred a straw-type lid but no more, this lid offers a great drinking experience. This bottle does what it's meant for - keeps things hot or cold for ages. I mainly use it for cold beverages and it does not disappoint. My elderly dad was recently in hospital and I loaned my bottle to him because it was so much easier for him to use than a cup w/ a straw. Needless to say, I'll never see that bottle again. He loved it. I'm now ordering myself another. It's an investment for sure but it will deliver years of use.
