Frequently Asked Questions
What is the PKM2020?The PKM2020 is a standalone 304 stainless steel packed resonator with a 3.0 inch dual inlet and dual outlet configuration, designed to reduce exhaust drone in custom dual exhaust systems.
Will the PKM2020 fit my vehicle?This is a universal component intended for custom exhaust fabrication rather than a specific vehicle, so it can be welded into most 3.0 inch dual exhaust systems.
How does a packed resonator differ from an empty pipe?A packed resonator contains sound-absorbing material that dampens specific drone frequencies, while a plain pipe section does not filter sound at all.
Will the PKM2020 make my exhaust quieter overall?It primarily targets drone at certain RPM ranges rather than reducing overall volume, so the exhaust will still have a noticeable tone.
Does the PKM2020 require welding?Yes, it is designed as a weld-in component for a clean, integrated fit into a custom exhaust system.
What material is the PKM2020 made from?It is constructed from 304 stainless steel for long-term corrosion resistance.
Can the PKM2020 be used with an X-pipe or H-pipe?Yes, it is commonly paired with an X-pipe or H-pipe in custom dual exhaust builds to further refine the exhaust tone.
Does the PKM2020 come with a warranty?CORSA backs its stainless steel components with a limited lifetime warranty against manufacturing defects.
Installation Instructions
- Raise and safely support the vehicle to access the exhaust system.
- Determine the desired placement for the resonator within the custom exhaust layout.
- Cut the exhaust piping to the correct length to accept the PKM2020 inlets.
- Position the resonator so it sits level and clear of the chassis and heat shields.
- Tack weld the resonator in place and verify alignment.
- Complete full welds around each joint for a secure, leak-free connection.
- Inspect all welds and check clearance from heat-sensitive components.
- Start the engine and check for leaks before lowering the vehicle.
