Product Description

The CORSA PKM2001 Pro Series Packed Exhaust Resonator is a universal weld-in acoustic component designed for performance exhaust systems that use 2.50" diameter piping. Built from 304 stainless steel with a brushed finish, this resonator features a straight-through perforated core wrapped in high-temperature sound-dampening material to help reduce overall exhaust volume by approximately 4-6 dB while maintaining strong airflow. Its reversible design and robust construction make it well suited for custom builds, classic muscle cars, or aftermarket cat-back systems where sound control is desired without significantly hindering performance.

Installation requires welding the resonator into the exhaust piping, making it a permanent and secure solution for adjusting exhaust tone and midsound characteristics. Suitable for use alone to mellow the exhaust note or paired with CORSA PRO Series mufflers for a more controlled sound profile, the PKM2001 resonator is a versatile choice for enthusiasts looking to refine the acoustic signature of their vehicle. Always verify pipe diameter compatibility and consult with a qualified installer for best results.
