Enhance your Audi S4 by adding the ARMYTRIX Super Sport Stainless Steel Exhaust System. This system will increase power, reduce weight, and improve sound. This precision-made performance system delivers more power, especially in the low and mid rev range, the effect on the sound is significant, adding a deep resonant sporty sound, but at the same time neutralizes the annoying frequencies in the most critical rpm range. Complete the look with a set of four sporty chrome polished silver tailpipes. 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 backpressure 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. When car owners turn on the race mode (valves opened), the gas goes through the section of straight pipes. This is where you get the incredible race sound and performance gain. In full throttle and it' straight pipe all the way, which means you will be expecting the LOUDEST sound performance you' ever hear! Includes:
  • Front pipe
  • Mid pipe
  • Valvetronic mufflers
  • Tail pipe
  • Remote control module

  • Stainless Steel

Great kids' shoe — easy on, comfy all day
Size: 3 Little Kid, Color: Pink/Lavender
My kid has been wearing these for a few weeks now and I'm genuinely impressed with how well they've held up. The knit mesh upper keeps feet cool and comfortable during long days at school and outdoor play, and the cushioned EVA midsole does a great job absorbing impact. What really won me over is the slip-on design with elasticated laces and dual pull tabs — my child can put them on and take them off completely independently, which is a huge win. The fit is snug but not tight, and they run a bit roomy in width, which is great for kids with wider feet or those who need a little growing room. At $32, the quality feels solid for the price. Lightweight, breathable, and easy to wear — these check all the boxes for an everyday kids' shoe.

Cute, Comfortable, Light-Weight Shoes, Perfect for School
Size: 11 Little Kid, Color: Pink/Lavender, Size: 11 Little Kid, Color: Pink/Lavender
These have turned out to be great everyday shoes for my 5 year old. She normally wears a size 10, but since that size wasn’t available, I ordered the 11 expecting her to grow into them. I was pleasantly surprised that they already fit her pretty well. There’s still a little extra room in the toe area, but the shoes fit securely around her ankles so they don’t feel loose or slip off while walking or playing. She says they’re very comfortable and loves how easy they are to slip on by herself. The lightweight design is nice for everyday wear, and they’ve held up well so far despite being worn almost daily. They've become her favorite shoes to wear! Also the pink/lavender color is really pretty in person. Overall, I’m very happy with them and would order again.

Great shoe well made
Size: 13 Little Kid, Color: Pink/Lavender, Size: 13 Little Kid, Color: Pink/Lavender
Really good shoes at a fair price. My daughter loves the pink and purple gradient colors. Really beautiful. Shoes have proven themselves very durable. She's been wearing these a few times a week for the last couple months and they still look new aside from some dirt stains. Fit perfectly. Very comfortable. This is always her first pick in the morning when she's getting dressed. Good breathability you can wear these in hot summer weather without sweaty feet. Versatile shoe looks good enough to wear out and about or exercise in.
