Exhaust drone at cruising speed is one of the most common complaints after installing a free-flowing exhaust. This universal resonator is built to be welded or clamped into a 2.5 in. system to knock down that droning frequency without choking flow, making it a good fit for custom builds, muffler-delete setups and performance exhaust projects on cars and trucks.
