Quiet down your exhaust note and keep spent gases flowing with the Walker Exhaust Resonator and Pipe Assembly, MPN 56039. This combined resonator-and-pipe unit tunes and dampens exhaust sound while carrying gases along the exhaust path toward the tailpipe, giving you a factory-style replacement for a rusted-through, rattling, or leaking original section.
- Resonator + pipe in one: the resonator chamber cancels unwanted drone and tone while the welded pipe routes exhaust flow downstream.
- Direct replacement section: installs in place of a corroded or damaged original resonator/pipe assembly.
- Restores a sealed path: helps return the exhaust system to a leak-free, properly quieted condition when the old section has failed.
Signs this section may need replacing include a louder or droning exhaust, a hissing or ticking leak, and visible rust-through or cracks along the pipe or resonator. Diagnose the source of any leak or noise before ordering, since other exhaust components can produce similar symptoms.
