A resonator is the simplest way to take the drone out of a free-flowing exhaust without giving up flow. This universal 4 in. resonator installs in-line on custom or aftermarket systems and uses a louvered core to cancel the harsh frequencies that build up at cruising speed, making it a good match for muffler-delete setups, straight-pipe builds and performance exhaust projects.
