Vibrant designed the Ultra Quiet Resonator for exactly that problem on six and eight cylinder engines. Its body is a flattened oval with far more internal volume than the small round bottle resonators most shops use, and that extra chamber gives the sound absorption material more room to work on low frequency drone.\u003c\/p\u003e\n\u003ch3\u003eConstruction\u003c\/h3\u003e\n\u003cp\u003eInside is a straight-through perforated core, so the resonator adds no meaningful restriction to a 3-inch system. The core is wrapped in multiple layers of sound-suppression material, and the whole case is T304 stainless with a mirror polish. The inlet and outlet are centered on the body, which makes it easy to fit in the straight section of a single 3-inch pipe.\u003c\/p\u003e\n\u003ch3\u003eDimensions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: Vibrant 1142\u003c\/li\u003e\n\u003cli\u003eInlet\/outlet: 3 in., centered\u003c\/li\u003e\n\u003cli\u003eOverall length: 13.75 in.\u003c\/li\u003e\n\u003cli\u003eBody: 6.5 in. x 4.75 in. oval, 9.75 in. long\u003c\/li\u003e\n\u003cli\u003eMaterial: T304 stainless, polished\u003c\/li\u003e\n\u003cli\u003eWarranty: 5-year limited\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003ePlacement changes the result, so if you can, clamp it in a couple of positions and test drive before final welding. Hang the resonator so the pipe joints are not carrying its weight, and back purge when welding the stainless joints.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eWill it make my exhaust quiet overall?\u003c\/h4\u003e\n\u003cp\u003eIt is aimed at drone and harsh rasp rather than overall volume.
