Namely, it replaces the rear axle-back and tips and then a portion of what we refer to as the mid-pipes. This system is emissions friendly and doesn’t require any tuning. In New Jersey, vehicles must pass emissions testing to ensure they meet environmental standards. Since cat-back exhaust systems do not modify the catalytic converter or engine management system, they generally do not affect a vehicle’s ability to pass emissions testing.
Typically, this includes the pipe connecting the pipe from the catalytic converter to the muffler, the muffler, and the tailpipe or exhaust tips. 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.
When it comes to improving your vehicle’s performance, you have two options. However, stainless still can be very expensive, as opposed to aluminized steel which is very affordable. It is also resistant to corrosion, just not to the level of stainless steel. Since there is no back pressure and the diameter is large enough, the engine will not use a lot of energy to push the exhausts out. While getting a cat-back performance exhaust system can be pricier initially, it can save on a lot of costs in the future. These exhaust pipes are usually wrapped in sound-absorbing materials, mostly fiberglass packing.
