Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars.  Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly.  The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. The factory catalytic converter is made up of catalyst material formed into "honeycomb" weaves. Exhaust gas must pass through these tiny "honeycomb" weaves on their way to the exhaust system thus causing a major exhaust flow restriction. It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction). By replacing the factory downpipe/catalytic converter with our Sports Series High Flow Metallic Catted Downpipe, more power is unleashed! 

We use a 200 cell metallic core for our Sports Series High Flow Catted Downpipes. By having less cells per square inch, these individual "cells" are bigger in size thus allowing exhaust gas to pass through it more easily. Thus, the lower the cell count, the higher the flow. Higher flow = more power, faster turbo spool up (less turbocharger lag) and better throttle response. Bottom line, faster. The benefits of a metallic catalytic converter vs a ceramic like the factory is that it can take higher temperatures and is more durable (last longer). They are also lighter than their ceramic counterparts.

Our Sports Series High Flow Catted Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by our in-house fabricators and built in the USA.  The factory turbocharger turbine housing utilizes a 3.5" V-Band flange which we have duplicated and CNC machined cut out of billet 304 stainless steel.  Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods.  The O2 sensor is positioned at the factory location. 100% bolt on. 

Our downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system.  There are no compatibility issues whatsoever.  The downpipes will come by default with brushed finish.

OPTIONS

Ceramic Thermal Coating - The purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out. This keeps underhood temperatures lower and less heat absorption by nearby parts/surfaces.  Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure. The ceramic coating also adds additional corrosion resistance. We utilize the best ceramic coating possible. Our thermal coating can resist up to 2000F of heat. It is available in black only (all the other colors cannot withstand the high levels of heat).

Great , fluffy pillows
Size: Queen / Standard, Color: White
They came compressed into a small roll so I was wondering how they would do. BUT they fluffed up to incredible size and comfy feel. I am impressed so far!

Pillow comfort and quality
Size: Queen / Standard, Color: White
Bought this for my husband. He is very happy with it. It is well constructed. He doesn’t like too firm or too soft. It meets those requirements. Very reasonably priced. I have bought very expensive pillows that aren’t even comfortable!

Pretty good.
Size: Queen / Standard, Color: White
Me and my fiancé have been going through a lot of pillows, trying to find the right ones. We go to this local hotel to unwind and use the whirlpool sometimes. Their pillows are immaculate. So I starting looking at “Hotel Pillows”. These are not the same as the hotel pillows, not even close tbh, but they are the best ones I’ve bought so far. They are comfy from day one. I was worried when opening the box and seeing that they had the same cover on them as others I bought before, but they were not the same. Pretty comfortable, and less neck pain than any of the other ones. My house is like the house of pillows and I am finally going to start getting rid of the old ones. Maybe we’ll find some down pillows to put on our registry, but until then, these are staying on my bed.

Finally a pillow that works – excellent neck support
Color: Crescent White, Size: Queen
After trying and spending money on several pillows over the years, this is the first one that has truly worked for me. What makes this pillow stand out is the adjustable fill. Being able to customize the height and firmness made a huge difference in finding the right level of support for my neck and shoulders. The crescent shape is also very comfortable and helps keep my head and neck properly aligned while sleeping. Since using this pillow, I have noticed a significant improvement in comfort, especially around my neck. It provides support without feeling too firm or too soft, and it maintains its shape well throughout the night. The quality of the materials is excellent, and the pillow feels durable and well made. I appreciate that it can be adjusted to fit different sleeping preferences rather than being a one-size-fits-all pillow. Pros: * Adjustable fill for a customized fit * Excellent neck and shoulder support * Comfortable crescent design * Maintains its shape well * High-quality materials Cons: * None so far Overall: This is the first pillow that has truly worked for me after trying many others. I highly recommend it for anyone looking for better neck support and a more comfortable night’s sleep.

Very nice pillow
Color: Cut-out White, Size: King
I was skeptical of spending this much money on a pillow, but so far I'm glad I did. It's very comfortable, and the shape does seem to help. I injured my neck/shoulder years ago, and I would wake up 1-2x per week heading slept wrong making my neck and shoulder stiff and painful in the morning. This pillow has so far prevented that. This pillow has also significantly reduced my snoring, according to both my Samsung watch and my wife. I'm a side sleeper. This pillow can be as firm or soft as you want since you can add or remove filling. It comes with a bag of extra filling just for that. I wouldn't say its cooling, but it certainly isnt too warm either. And I'm someone who sleeps hot. All in all, I'd buy it again.
