An internal combustion engine uses oxygen just as fires require oxygen to keep aflame. There is no internal oxygen tank in a car for this purpose, as that wouldn’t be very efficient. Instead, Audi vehicle manufacturers equip cars with intakes that bring air inside to the Audi engine directly. Audi Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the Audi car all the way to the engine, though stock versions aren’t always the most effective.
For that reason, many car owners turn to aftermarket Audi air intakes to increase the effectiveness and efficiency of their vehicles’ intake capacity. The greater the amount of oxygen supplied to the engine, the more power it can produce. Audi Cold air has more oxygen, for instance, so Audi cold air intakes have become popular Audi intake upgrades. Other upgrade types focus more on greater Audi air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Audi air intake system in your car.

My impala looks better than ever! the ride is not as bouncy as my other set of spring and the height is just perfect

This straight pipe is very nice. I bought 1 myself for me 85 Corolla and it sounds really nice also. I don't use the silencer as much but besides that everythings nice. I'm 15 right now and I'm trying to get somewhere with my 85 Corolla that me dad loaned to me. They straight pipe I bought just killed it. Its really awesome!

Was a little worried about getting this exhaust because of the amazing price, but was really surprised. Shipping was fast. less than a week. Install was easy, bolted right up, everything where it's supposed to be. Looks really good on my car and sounds great. Nice deep sound, not buzzy. Loud but not TOO loud. Noticed the power increase immediately. Really good exhaust for those of us on a tight budget.
