Series 57 Design
The Series 57 is the largest round-body muffler in the Cortek lineup, featuring a 5.7-inch diameter body. Despite its larger size compared to other round models, it remains compact and versatile, making it suitable for a wide range of exhaust system layouts.
Because of its size and internal volume, the Series 57 provides improved sound attenuation compared to smaller round resonators, while still fitting easily into many performance exhaust systems.
Flexible Installation
Round-body mufflers offer a significant installation advantage. In applications using offset configurations, the muffler can be rotated 360°, allowing installers to route exhaust piping around obstacles such as:
This flexibility makes the Series 57 particularly well suited for custom exhaust fabrication and performance builds.
Typical Applications
The Series 57 is commonly used as:
-
A resonator in performance exhaust systems
-
A primary muffler on sport compact vehicles
-
A muffler solution for performance trucks
-
A sound-control component in custom exhaust systems
Its internal design helps reduce unwanted exhaust noise and vibration while maintaining smooth exhaust flow, preserving overall engine performance.
Durability
Manufactured from T304 stainless steel and hand TIG welded, the Series 57 provides:
-
Excellent corrosion resistance
-
High structural integrity
-
Long-term durability in demanding performance environments
Summary
The Cortek Series 57 Round Muffler / Resonator combines compact packaging, strong sound control, and flexible installation options. With its 5.7-inch round body, it offers greater sound attenuation than smaller resonators while remaining highly versatile, making it an excellent choice for performance exhaust systems, sport compact applications, and custom fabrication projects.
