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.

These two work together to offer better flow and allow the system to breathe better. We are one of few brands that own our factory thus enabling us full control over the manufacturing process, selection of raw materials, and construction techniques. Install your IE catback without any permanent modifications or installation hassles. The installation process is straightforward and accomplished with standard mechanic tools.

But with so many options available, it's easy to get lost in the world of aftermarket exhaust systems. While some companies may try to lure customers with an attractive price tag or flashy branding, it's quality of performance, sound, and construction that truly sets a great brand like Invidia apart from the rest. Transform your vehicle with the Roush Performance F-150 Cat-back Exhaust System, an ideal replacement for your factory exhaust system. Crafted from robust, corrosion-resistant T-304 stainless steel, this system features high-flow mandrel bends to enhance exhaust flow efficiency. Experience the thrill of enhanced acoustics and performance with this premium upgrade for your F-150. Banks patented exhaust systems enhance power, fuel economy, and sound by removing all airflow restrictions.

Engines fitted with regulated 3-way catalytic converters are equipped with a computerized closed-loop feedback fuel injection system using one or more oxygen sensors (also known as Lambda Sonds or sensors). Other variants combined three-way converters with carburetors equipped with feedback mixture control were used. An unregulated three-way converter features the same chemical processes but without the oxygen sensor, which meant higher NOx emissions, particularly under partial loads. These were low-cost solutions, typically used for retrofitting to older cars or for smaller, cheaper cars. Axle-back exhaust systems replace only your vehicle’s rear exhaust section, usually consisting of items behind the rear axles, like rear exhaust pipes, muffler, and exhaust tips. A&nbsp
