Description
The Borla CrateMuffler Resonator Option (Part Number 400939) is an ideal solution for vehicles with limited space, providing effective sound attenuation without compromising performance. Designed with a straight-through flow path, this resonator helps reduce overall sound levels by approximately 2-3 decibels (dB(A)), delivering a quieter driving experience while maintaining optimal exhaust flow. Crafted from high-quality T-304 austenitic stainless steel, it offers superior corrosion resistance and durability, ensuring long-term reliability even under harsh conditions. The resonator’s 100% welded construction enhances strength, and its free-flow design supports improved exhaust performance, making it suitable for a variety of applications and systems with the same diameter.
The resonator features a reversible, universal design for flexible installation options, allowing for easy integration into different exhaust configurations. Its natural mill finish can be customized through brushing or polishing to match your vehicle’s aesthetics. The 4-inch round body measures approximately 10 inches in length with an overall length of about 14 inches, making it compact yet effective for space-constrained setups. The un-notched necks are intended for weld-in installation, although clamp options using 3-inch wide band clamps are available for easier mounting. Compatible with Borla’s S-Type CrateMuffler, this resonator helps achieve a touring sound level for a balanced exhaust note.
Manufactured in the USA, the Borla CrateMuffler Resonator Option is backed by Borla’s Million-Mile warranty, reflecting its quality and reliability. This resonator is not CARB approved but is designed to meet general exhaust sound reduction needs. Its universal fit and reversible design make it a versatile choice for automotive enthusiasts seeking to control exhaust noise without sacrificing performance or durability. Whether you’re upgrading your exhaust system or seeking a quieter ride, this resonator provides an effective, high-quality solution that aligns with Borla’s reputation for excellence in exhaust technology.
