ARMYTRIX believes each super-car deserves an ultimate lightweight "aero-grade" titanium exhaust for the best performance and exhaust sounds upgrades, not just a heavy steel made exhaust systems. ARMYTRIX has spent hundreds of hours of development and sound tuning to unlock the perfect combination of exhaust tone, sound volume and practicality. The valved exhaust system which was specifically designed to unlock power hidden in the 4.2L/5.2L engine and produce a much more aggressive and characteristic exhaust sound. Another great benefit of the R8 system is that it' so much lighter than the factory exhaust, shaving nearly 21 kilogram of dead weight from the rear of the car, ARMYTRIX achieved this by using aero-grade titanium throughout the entire system and of course, the titanium racing exhaust delivers the best sound for each individual owner at all revs without needing manual switching; this is an unmatched piece of performance engineering. ARMYTRIX exhaust systems differ from other brand' exhaust systems with their unique "Throttle Pedal Sensor and Engine RPM Signal Auto Functions". Through this system ARMYTRIX offers car owners a better launch-start without losing back pressure by automatically closing the valves at low rpm. When your car is driving at high speeds, the valves will automatically open to increase air flow for better performance (hp & torque gained) and sound. Car owners can set their own timing for valves to automatically open and close by engine rpm and how deep they press the gas pedal. It' a new innovative system that brings your car to a different level. With the ARMYTRIX you are not getting just an exhaust system, you are getting a driving system unlike any you have experienced before. Includes:- Titanium X-Pipe Mufflers

Comfy and so cute.
Size: One Size, Color: Skyway, Size: One Size, Color: Skyway
This alpaca beanie is just plain cozy. Super soft, comfy, and surprisingly warm. It fits well (the one-size actually works), and it sits nicely without feeling tight or slipping around.
I get compliments every time I wear it. Great for cold days, football games, or just when I want something cozy with a little personality.

Very comfortable
Size: One Size, Color: Heather Beech
How I Use It:
I’ve been using this beanie for two months.
Features that stood out to me:
The beanie works great; and I also really liked the knitting; it really holds together well and stays on your head. The material is soft and really keeps your head warm while also breaths, so your head doesn't get too sweaty.
My Personal Experience:
If I compare this one against the others I’ve used, this one is just plain better. I wasn’t expecting to like the actual cashmere material as much as I do.
Pros and Cons:
What was good: cashmere soft and warm, great construction, nice color, affordable
What was not good: none
Durability:
After two months, it still does its job the first time every time with no fuss. I can’t really ask for more.
Final Thoughts:
Overall, it has been good for me and my needs, and I’d buy it again.

Very warm beanie
Size: One Size, Color: Wine, Size: One Size, Color: Wine
This hat is very well made and super warm. I have not worn it while it was snowing or raining, so I’m not sure how well it would hold up if it gets wet. However, I hand washed very gently with some woolite followed the instruction for drying and it dried well. The color is a nice deep plum. It is folded at the bottom and can be adjusted to cover ears or accommodate a longer head shape. The material is as you would expect of cashmere and soft. It still has a good knit structure and doesn’t get stretched out. It’s a little bit of a lint and hair magnet though, so might need a lint roller (especially if you have dogs or cats). I’m just shocked by how warm it keeps my head and ears in temps that are in the teens, even with wind. Very happy with this hat.

super comfy and CASHMERE beanie!
Size: One Size, Color: Black
This beanie is fantastic. The cashmere knit is incredibly soft and warm without being itchy at all. This feels great even after wearing it for long periods. I also really appreciate the minimalist design in that there were no huge brand logos or any crazy graphics on it. The clean silhouette and folded cuff make it easy to pair with just about anything. It’s simple, comfortable, and looks great.

One of the softest things I own
Size: One Size, Color: Black
This Cashmere hat is the softest hat I have ever worn. It is not thick, and it is super stretchy, so fit really is one size fits most. It is incredibly warm. I love natural fibers, as they feel so much better on your skin, and they just work better (I live in a cold climate). This hat has a tiny bottle of nylon/elastsne to make it hold up better and fit better, but it's mostly Cashmere (94%). The wash instructions are simple: hand wash in cold water, roll in a towel, amd block/reshape. Amazon always likes me to comment on value for price on these reviews, and to be honest $98 (the price it was selling for when I ordered it) is rather steep. That is the only reason I didn't give that 5th star. I feel like this hat will last for a decade or more (if one of my kids doesn't steal it), so looking at it that way, the price seems more reasonable, but it is still a lot for a hat. Otherwise, I am absolutely in love with it. It's a little luxury in my winter wardrobe.
