Design Overview
The Series 45 is a compact muffler with a diameter of only 4.5 inches, making it ideal for installations where space is limited.
Despite its small size, the internal chamber design is highly effective at controlling low- and mid-frequency exhaust tones by managing and stabilizing the internal acoustic volume. Because of this characteristic, the Series 45 is particularly well suited for use as a resonator within a performance exhaust system.
Sound Control Characteristics
This model is especially effective at attenuating higher-pitched exhaust notes, helping to refine overall exhaust sound quality.
However, if your goal is significant overall noise reduction, it is recommended to pair the Series 45 with a larger rear muffler. Combining a smaller resonator with a larger rear muffler allows for improved suppression of both exhaust noise and vibration.
Performance Benefits
The Series 45 is designed to:
By minimizing restrictions while controlling unwanted frequencies, it helps preserve engine performance while improving exhaust acoustics.
Summary
The Cortek Series 45 is a compact yet highly effective muffler/resonator designed primarily for controlling low and mid-frequency exhaust tones in performance exhaust systems.
It is best used as a resonator in combination with a larger rear muffler for optimal sound suppression. Built entirely from hand-welded T304 stainless steel, it delivers excellent durability, corrosion resistance, and long-term reliability in demanding automotive applications.
