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, GMC Envoy vehicle manufacturers equip cars with intakes that bring air inside to the GMC Envoy engine directly. GMC Envoy Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the GMC Envoy 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 GMC Envoy 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. GMC Envoy Cold air has more oxygen, for instance, so GMC Envoy cold air intakes have become popular GMC Envoy intake upgrades. Other upgrade types focus more on greater GMC Envoy air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded GMC Envoy air intake system in your car.

Was ify after reading some things in forums about this site. But it was a very good buying experience. tje exhaust sounds great and really simple to install other than the pressed bolts on the first flange. shipping took a week.

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.
