Let Your Coyote V8 Breathe the Way It Was Built To
The Thermal R&D dual exit 3 inch catback exhaust is built for the 2021 and newer Ford F-150 5.0L V8 Coyote and improves exhaust flow by up to 78 percent over the factory system. A 3 chambered Helmholtz drone canceling muffler delivers a more aggressive V8 note under throttle while keeping the cabin quiet and drone free at highway cruise, so there is no need to shift into a higher gear just to escape resonance.
