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).

A cat back exhaust system, also known as a catback exhaust, is an aftermarket automotive exhaust system that replaces everything in the exhaust system from the catalytic converter to the tailpipe. Cat back exhausts are available in various configurations and materials, allowing drivers to choose the one that best suits their needs and preferences. An aftermarket cat back exhaust might be the perfect upgrade that can enhance your Dodge Charger’s performance and road presence. Unlike its OEM counterpart, it boasts a less-restrictive construction, so it can release more exhaust gases. A cat back exhausts is also designed to install behind a catalytic converter, so remains emission compliant. In addition, its design lets your vehicle generate a more distinct exhaust sound.

An upstream air injection point, ahead of the catalytic converter, is also sometimes present to provide additional oxygen only during the engine warm up period. This causes unburned fuel to ignite in the exhaust tract, thereby preventing it reaching the catalytic converter at all. This technique reduces the engine runtime needed for the catalytic converter to reach its “light-off” or operating temperature. Many vehicles have a close-coupled catalytic converter located near the engine’s exhaust manifold. The converter heats up quickly, due to its exposure to the very hot exhaust gases, enabling it to reduce undesirable emissions during the engine warm-up period.
