PROFILE
This A4 test pipe is a powerful and easy bolt-on alternative to a full downpipe exhaust upgrade. The ARM Test Pipe replaces the section of the OEM exhaust that is the most restrictive on the 2.0T, which is bolted directly onto the turbocharger housing. The OEM section of the exhaust is equipped with a catalytic converter from the factory, and by installing this upgraded catless exhaust section, your A4 will allow more airflow and decrease back-pressure, which can produce up to +24whp and +30wtq on tuned cars.
The improved power and torque is most noticeable lower in the rpm range where the stock system stifles exhaust flow. After installing the Test Pipe you will also experience increased throttle response and improved turbo spool because the faster flowing exhaust will spin the turbocharger quicker, which will result in hitting target boost levels faster. The result: faster acceleration, quicker 0-60mph and 1/4 mile times.

The result: faster acceleration, quicker 0-60mph and 1/4 mile times.
The ARM Test Pipe will also greatly improve the sound of the exhaust, even with the rest of the system in stock form. It's stunning to see how much the OEM exhaust not only kills power but also sound. After upgrading to an ARM Test pipe expect a deeper and more aggressive sound on your A4 2.0T.
CONSTRUCTION
The ARM Test Pipe is constructed of 3" Stainless Steel for high-flowing performance and longevity. Included are two O2 bungs where the factory O2 sensors can be reinstalled or blocked off with the two included bolts.If you are installing the ARM Test Pipe on a stock or stage 1 ECU tune, this now opens the doors to run advanced boost settings. With the high flowing 3" Test Pipe the 2.0T engine can now handle increased exhaust flow from higher boost targets.
If you run this system without an ECU tune or O2 sensor fix, expect to get a check engine light. This can be resolved by installing an upgraded ECU programmer or using an O2 sensor fix adapter.

Do not buy these
Color: Nude, Size: Women 9-13
These are terrible. They are designed to walk in. The first day I tried them on I walked about 20 steps and they basically ripped right off my feet. I didn’t think much of it and just thought ok I won’t walk in them I’ll just wear them to bed. The second pair that came with the order I wore to bed that night and woke up with holes tore in them. Terrible product

These are form-fitting and durable. Wearing these keeps the skin moisturizer in place so it can be effective.

Great Results
Color: White, Size: Women 9-13, Color: White, Size: Women 9-13
The Jfrhuds Moisturizing Silicone Socks work very well. I ordered the white 2-pack in the large size 9-13, and each came packaged in an individual zipper bag. I wear a women's size 9-9.5, and they fit me perfectly. I can see how they have enough stretch to fit larger sizes easily and comfortably.
These socks are a lot thicker and heavier than I expected. They are rubbery with non-slip treads on the bottom. As soon as I put them on my feet, they actually felt very moisturizing and almost wet, even though I had not put moisturizer on my feet first. Plus my feet felt cold at first. It was different than I expected, I had never worn this type of sock before, and it was an interesting sensation.
They work great, and I am sold on the benefits of these socks. I wear them to sleep at night and dodn't walk very far in them. They seem pretty sturdy, but I don't want to push it and will just use them for their intended purpose. My feet weren't super dry or cracked, but the socks really helped revive them and make them super soft again. I love them; they are great for self-care and would also make a wonderful gift.

Not durable
Color: Nude, Size: Women 9-13
Only used two of them so far. One sock lasted nearly 3 wears. The other broke before I could finish wearing it the second time. Basically useless junk.
