Discover MagnaFlow's latest evolution in performance exhaust technology. Stainless steel is the most popular choice for cat backs because it is durable and has a deep, throaty sound. But if you're looking for something lighter weight, you can also find cat backs made out of titanium. So, when it comes time to choose the right cat back for your car, keep these three things in mind and you'll be sure to find the perfect fit.

The new Large Bore-HD exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's. This system is available in 4" cat-back with muffler. Large Bore-HD exhaust systems are the perfect combination of performance, fit and value. For over 40 years, MagnaFlow has maintained its position at the forefront of high-end catalytic converter and performance exhaust manufacturing. MagnaFlow stands by its products with industry-leading warranties in service of its mission to provide the highest quality exhaust experience from start to finish.

Another difference is with the material used in the cat-back exhaust system against that in stock exhaust systems. But the problem with a resonator is that it can cause restriction to the flow of the exhausts. In the end, this can end up lowering your vehicle’s performance. It is also more affordable and easier to install than other types of exhaust systems, including the cat-back exhaust system. Cat-back and axle-back exhaust systems are both aftermarket exhaust systems. A performance exhaust system, like the cat-back exhaust, allows for easy splitting into dual exhaust.

While a cat-back exhaust system includes all components from the catalytic converter to the exhaust tips, an axle-back system only replaces parts from the rear axle to the tips. Axle-back systems are generally easier to install and less expensive but offer more limited performance improvements and sound changes compared to cat-back systems.
