Most designs of the time therefore included secondary air injection, which injected air into the exhaust stream. This increased the available oxygen, allowing the catalyst to function as intended. Cat-back exhaust systems replace every component behind the catalytic converter, including most piping, mufflers, resonators, and tailpipes.

Different exhaust systems offer different noise levels and tones, but how? Sound quality and overall loudness of an exhaust system can vary significantly depending on the pipe diameter, size and design of the muffler, resonator inclusion, and the number of outlets. For this reason, all systems sold on RealTruck are filtered by noise level, including loud, moderate, and quiet. From the factory, most manufacturers employ small-diameter piping, restrictive mufflers, and noise-reducing resonators, significantly smothering exhaust flow and sound quality. A front pipe back system replaces a few key components of the OEM Honda or Acura exhaust found on your EX, Touring, Si, or A-Spec that are after the Front Pipe (the pipe that goes under the engine).

They are usually the last systems to get addressed by performance drivers, who put a majority of work into turbo systems or custom tunes.

Although phosphorus is no longer used in gasoline, it (and zinc, another low-level catalyst contaminant) was widely used in engine oil antiwear additives such as zinc dithiophosphate (ZDDP). Beginning in 2004, a limit of phosphorus concentration in engine oils was adopted in the API SM and ILSAC GF-4 specifications. Although catalytic converters are most commonly applied to exhaust systems in automobiles, they are also used on electrical generators, forklifts, mining equipment, trucks, buses, locomotives, motorcycles, and on ships. They are even used on some wood stoves to control emissions.[5] This is usually in response to government regulation, either through environmental regulation or through health and safety regulations. Custom setups, especially for vehicles that do a lot of off-roading are also available.

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.
