{"product_id":"s58-4-5-single-midpipe","title":"S58 4.5\" Single Midpipe","description":"The ARM S58 4.5\" Single Midpipe is engineered to enhance the exhaust sound of your S58-powered BMW G8X M3\/M4.\n\nThis upgrade removes the secondary catalysts and two middle resonators, significantly improving the exhaust note to be deeper, richer, and more audible, even with OEM tuning. By retaining the OEM muffler, you maintain full control over the exhaust valves, allowing you to switch between a subtle tone and maximum volume.\n\nConstructed from SS304 stainless steel, the midpipe features a massive 4.5\" design from the downpipe connection, reducing to 2.75\" to mate with the OEM muffler. It utilizes an OEM-style 2-bolt flange compatible with stock or upgraded downpipes. The slip-fit connections and a unique merging section combine the sound waves from each engine bank for a distinctive tone. An OEM-style mounting bracket secures the midpipe during aggressive driving. This product is for Off-Road Use Only and is intended for racing vehicles.\n\nThe ARM S58 Midpipe is designed for the BMW G80 M3, G80 M3 Competition xDrive, G82 M4, G82 M4 Competition xDrive, G83 M4, and G83 M4 Competition xDrive, all equipped with the S58 3.0L engine. It also includes ARM Downpipe Gaskets, an ARM Extended Brace, and ARM Clamps in the box. ARM Motorsports backs this product with a lifetime warranty against defects in craftsmanship or fitment.","brand":"ARM","offers":[{"title":"Default Title","offer_id":52686962786616,"sku":"S58MID","price":762.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660183612.webp?v=1784878999","url":"https:\/\/store.motormia.co\/products\/s58-4-5-single-midpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
