B58 lovers, REJOICE! 🙌👏 Let’s be honest—what’s the point of owning a B58-powered BMW if you can’t hear it? The factory M340i and M440i rear muffler assembly is oversized, heavy, and overly restrictive, muting the deep, aggressive tone the B58 engine was designed to produce. Our Muffler Delete System is the perfect solution for enthusiasts looking to unleash that signature turbocharged inline-six sound without the cost of a full cat-back system. #bmw #b58 #turnermotorsport #m340i #ecstuning
