Everything needed to complete the installation is included. Each system includes the mufflers, pipes, hangers, and the 304SS polished tips you choose, plus all of the necessary instructions and information for installation.
Performance varies by the vehicle and system chosen. On average, Corsa systems will deliver a 3-5% increase in horsepower, though this may vary by vehicle. For example, the Corvette systems will on average give an increase of 17-19 hp. In addition to hp increases, Corsa systems will dramatically increase free airflow, allowing your other performance modifications to achieve their full performance potential.
Corsa systems are specifically designed for every vehicle make, model, type and even transmission to deliver the best sound, with no drone, and maximize performance. Larger pipe is not always best and the company chooses the diameter pipe that best suits a vehicle to maximize the outcome.
Corsa uses only premium grade stainless steel in all of their Corsa products. This includes not just the pipes and mufflers, but the hangers and clamps as well.
While many of Corsa customers have noticed significant improvement in gas mileage, scientific testing has yet to be completed. Driving style has much to do with gas mileage and some customers just can't keep their foot off the gas.
An XO-crossover pipe allows the exhaust flow from both banks of the engine to mix and balance out, which creates improved flow characteristics and a more pleasing exhaust note. It can also help reduce some of the trailing throttle burble characteristic of certain engines. In some cases, the blending of the exhaust can help accelerate the exhaust gases enough to improve the scavenging of the combustion chamber and free up a few extra hp.
An XO-crossover pipe brings the two exhaust pipes together in an "X"-shape for a true cross-over between the pipes. An H-pipe keeps the flow paths separate and simply tries to balance the exhaust gas pressure and flow; these are often referred to as "balance tubes." Corsa crossover pipes are designed to reduce turbulence and blend the air to create the most performance and perfect Corsa sound.
Yes, all Corsa systems are designed for ease of installation, but it really depends on the vehicle and your mechanical aptitude. Some vehicles are easier to work on than others, but if you have the right tools, a little patience and you read the full color instructions, just about anyone can do the job. Having a lift to raise the car and a friend to help handle the larger components is highly recommended if you decide to install the system yourself. Typical installation times range from 1 to 2 hours.
Most systems do not require any physical modifications to your vehicle to allow installation. In many cases, other performance modifications done to the vehicle; i.e. air intakes, programmers, etc. will show additional benefits/gains with the installation of a Corsa performance exhaust system.
No update to the ECU is needed when installing a Corsa performance exhaust system; although retuning of the ECU using an aftermarket programmer or custom tune may yield even greater hp and torque gains.
No, check engine lights or error codes are activated by the proper installation or use of a Corsa performance exhaust system.
Be aware that welding a Corsa system that is designed to be clamped together will void your Corsa limited lifetime warranty. Welding will also prevent you from making adjustments to the system as it "settles" after a few heat cycles.
In most cases, no, but some Corsa kits require 1-2 simple cuts to facilitate removal of the old system. Everything is covered in each set of detailed installation instructions, complete with full color photos. Some trucks and SUVs do require cutting of the factory systems to allow for their easy removal from the vehicle.
Each sound is designed to offer customers a choice to find the right sound for them.
RSC™ or Reflective Sound Cancellation™ is Corsa’s patented technology that uses scientifically proven passive noise cancellation principles to facilitate the elimination of select low frequency sound waves that can cause drone or resonance in vehicles.
Drone (also known as resonance) is the byproduct of low frequency sound energy generated by the engine exhaust interacting with the body structure of the car. This sound energy generated by the engine and flow noises is amplified by the trunk and cabin cavities at certain rpms, resulting in a low frequency, dull and thrumming sound that can be very annoying. Certain low frequency sounds can even make people sick and nauseous. This is the drone or resonance people refer to when talking about most aftermarket exhaust systems. You will typically not experience this drone when at idle or accelerating hard, but in exhaust systems not using the patented Corsa RFC™ technology, the drone becomes very apparent at highway cruising speeds.
Recorded sounds vary greatly due to the recording equipment, quality and the speakers through which it is played. Corsa’s best recommendation is to find a friend or a car club to hear something in person as that will give you the truest Corsa experience.
