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).
Since 2003, we have specialized in building BMW M-models (and Tesla) with a refined selection of industry-leading, high quality products. Our 8,000 sq/ft installation facility and shipping headquarters is located in Anaheim, California. IE's advanced DroneTrap technology captures the pulse waves responsible for your B9 3.0T engine's exhaust note and draws them into dual mathematically tuned resonators. The internal ports are engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drones.
Considering cat-back exhausts replace more restrictions, they typically offer increased performance and noise compared to axle-back systems
