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.
