I installed a Gibson Swept side exhaust on my 2017 Silverado 5.3L and it was too loud and making an annoying hum at 1700-2000 rpm. I removed the attachment that came with it and replaced it with this one and am very happy with the result. The sound of the exhaust deepened and softened, and the rumble almost disappeared. I would recommend this resonator tip to anyone having drone issues or needing to tone down the exhaust tone.
