Unlike your stock system, CORSA exhaust systems don't utilize performance-robbing restrictions that reduce airflow, such as chambered designs, baffles or spring-loaded valves. 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.
The only difference is that it features straight perforated pipes. The original exhaust systems focus more on just reducing the sound and not shaping it to give it that desired deep growl. One function shared with both the axle-back and the cat-back exhaust systems are shaping your vehicle’s tone.
This quality material will ensure that your Cat-Back system will last through any harsh conditions. A cat back exhaust system is a form of car exhaust that includes the catalytic converter. This type of system is often used by those who want to improve their car's performance, as it can help to increase power and efficiency.
Federal Catalytic Converters are not legal for sale, installation or use in the state of California. It should be noted that a split system will often provide an aggressive noise increase, and some designs will split the two pipes to opposite sides of the vehicle. If you are looking to save a little money but still get most of the benefits of a cat back exhaust system, however, aluminized steel may be the way to go. Made from traditional steel that’s been coated on all sides with aluminum-silicon alloy, these systems are very strong thanks to the metallurgical bond which still provides a level of corrosion resistance. While the aluminum coating reflects heat well, the steel can corrode if the aluminum layer is chipped or scraped off. Most cat-back systems will come in either an aluminized or stainless steel version.
Dual Magnaflow wide open mufflers with quad 3.5" exhaust tips, slightly louder and deeper than standard Borla. This upgrade option retains the large Borla resonator and replaces Borla mufflers with dual Magnaflow mufflers and quad tips. Borla is a great exhaust, but with this upgrade your back will look much better with the large aggressive oval quad tips and will sound better too! Cat-back exhaust systems refer to all of the components that exhaust gasses flow through after exiting the vehicle’s catalytic converter.
Walker is your one-stop exhaust shop, offering a full line of mufflers, pipes, hardware and accessories. Cat to Y pipe intersection showing after cat O2 sensor location. This qualifies as one of the STRANGEST stock exhaust parts I have seen. For some reason Toyota/Lexus decided to weld a straight section of 60mm pipe to the cat outlet flange, angle cut it, weld a 50mm pipe pipe that has its last couple of inches expanded to 60mm and match angle cut. Also note the O2 placement is in the 50mm sections of the Y pipe where the sensor tip takes up a good portion of the available flow area.
The cat back system’s pipes have a larger diameter than a standard set. So, your vehicle will get to perform better at a fraction of the work it outputs. An
