So, how do we achieve these incredible sounds? It's all in MRT's sound engineering process that involves a deep understanding of how gases flow and resonate through the system. By strategically implementing specific muffler designs, resonators, and pipe diameters within our axle back, mid-pipe and cat back configurations, we sculpt the sound waves to maximize performance and minimize exhaust gas back pressure.

The sound engineering designs are delivered via a handcrafted manufacturing process. We use mandrel bend exhaust tubing for smooth gas flow paths and premium T304 stainless steel for improved corrosion resistance. Whether it's an axle back or a full catback system, we focus on crafting a quality sound that has character and complements the vehicle's personality; not just hitting a certain decibel level.

MRT is committed to giving you a carefully orchestrated performance sound that enhances your driving experience and makes your vehicle sound exactly as it should - FULL TIME COOL! It's the art of sound engineering that transforms a simple exhaust system into a symphony of performance where you can Hear the Difference, Feel the Performance and Get Noticed.
