One main reason for choosing to remain with a stock system is because it comes already installed on your vehicle. You should know the difference between a dual exhaust and a dual exit exhaust system. But it is easy to mistake a dual exit exhaust for a dual exhaust system. The materials are often 304 stainless steel or aluminized steel. The stainless steel is usually coated in special metals that make it corrosion-resistant. This means there will be a reduction in the amount of load on the engine, leading to higher mpg and fuel efficiency.

Because these types of exhaust systems are installed after the emissions monitoring systems of a vehicle, they won’t impede its ability to measure emissions. However, you must be aware of your local noise regulations and adhere to them. With relatively short install times when using a high-quality system from MagnaFlow, exhaust modifications can yield the instant gratification of your ride sounding as fast as it looks. When you purchase an aftermarket exhaust system like a cat-back exhaust, you're in control of horsepower and sound output as pipe diameter and muffler type are in your hands.

With wider tubing and our mandrel-bent design, your new full exhaust system will allow for reduced backpressure and provide cleaner oxygenized air to your engine. You'll see benefits like increased horsepower, torque boost and better fuel economy.
