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
  • Y-Pipe
  • Valvetronic mufflers
  • Tail pipe
  • Remote control module

Fun educational book
Format: Hardcover, Format: Hardcover
This book is a big hit! My 5 year old son and I read it so many times since we ordered this in April. It has cute illustration and 60 flaps and pop-ups which make the book even more exciting. And because of this, I don’t recommend this book to young kids under 3 though. Some flaps might be tricky for younger kids. Even I as a parent learned so much about construction.

Great book, but the other book of the same author is much better
Format: Hardcover
This is a very high quality book, chock a block full of information about construction sites, with lots of imaginative flaps, things that swivel, move, and fold. HOWEVER...it is not as good as "The Ultimate Book of Vehicles" by the same author. The "Vehicles" book is more appropriate for kids 3 years and up: It is still full of awesome flaps, swivels, and things that move, but it is simpler, with pictures of the vehicle, the name of the vehicle, and maybe a few names of the parts of the vehicle. You open up a flap to see inside, make it move, etc. My son found it very interesting. The "Construction" is really aimed for older kids, I'm guessing 5 and up, maybe even older. There are just so many words on the page, and so much information. The flaps are not as interesting as the previous book, and I found many of the moving parts to be "sticky", and my 3 year old ripped quite a few out within a week of reading the book. We have not ripped anything from the "Vehicle" book. So I would say if you have an older kid who wants to gain a lot of knowledge about construction sites, this book is for you. But if you have a younger child (3 and up, any younger and they'd destroy the book), get the "Vehicle" book.

So Much Fun And Very Informative
Format: Hardcover, Format: Hardcover
This book has been a winner in our house since it arrived. Each page has so many flaps, spins, pulls and movement. So many new words and easy explanations for the kids. The pictures are beautifully designed and each time we look through it we find more details we missed! The book is an excellent purchase and definitely worth every penny!
