Enhance your Audi A4 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
- Quad Chrome Coated Tips
- 3 Mode Valve System to control exhaust sound

Holistic Dentist Recommended & We’ve Seen a Big Difference
Flavor Name: Mint, Size: 3.4 Ounce (Pack of 1)
Our holistic dentist recommended Dr. Jen’s fluoride-free toothpaste with 10% nano-hydroxyapatite after my daughter had struggled with quite a few cavities. We wanted something that would help strengthen and support her enamel without fluoride, and this was the product she specifically suggested.
One thing I really like is that it’s a non-rinse formula. After brushing, she just spits and doesn’t rinse, so the nano-hydroxyapatite can stay on the teeth longer to help support enamel. That gives me extra peace of mind knowing it’s continuing to work even after brushing.
The texture is smooth and not gritty, and the flavor is mild enough that she actually uses it without complaining. Since switching, her teeth look clean and healthy, and we feel much better about her cavity prevention routine.
The only downside is the price — it’s definitely very expensive and one of the most expensive toothpastes out there. But for us, given the dentist recommendation and the peace of mind, it’s been worth it.

Hopefully it strengthens the Tooth Enamel!
Flavor Name: Mint, Size: 3.4 Ounce (Pack of 1)
Excellent Product: I've been using its for a couple months and the flavor is fantastic. Ideally, you don't want to rinse it off your teeth so that the Active HA coats them and stays on for a while (especially at night). I've been recommending it for my patients in my office, and will see if it stops some of the smaller cavities. I'm not a paid Sponsor but love the product

Very expensive, but a good product
Flavor Name: Mint, Size: 3.4 Ounce (Pack of 1)
I like it, it seems to clean great and the flavour is good. I like that it foams more than other tooth paste. I tried it to see if it helped my wife sensitivity but it didn't, so I won't spend this kind of money on it.
