Not only is the tone improved but the additional burbles and pops that come with it are simply intoxicating. Dinan also incorporates a Helmholtz chamber design that reduces resonance or\"drone\" at low RPM.\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":50916371431591,"sku":"DNND660-0067","price":1660.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/8344\/1063\/files\/2e256ffe93eede161dc3b4f75ef058caL_256236d6-83a7-4cd7-a102-db95b9e61fb6.jpg?v=1782491023","url":"https:\/\/www.straightsiximports.com\/en-us\/products\/dinan-17-21-bmw-m240i-freeflow-axleback-exhaust-system-polished","provider":"Straight Six Imports","version":"1.0","type":"link"}
