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:

Reduce exhaust noise and vibration

Refine exhaust tone

Maintain smooth, uninterrupted exhaust flow

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.
