The X-Pipe or H-Pipe section lives above the OEM brace with ample clearance, there is no need to install a larger brace. <br></p> <center> <div class="embed-container"><iframe src="https://www.youtube.com/embed/QN4DgnvZmg8"></iframe></div> </center> <h1 style="text-align: center;"><br></h1> <p style="text-align: center;"><strong><br></strong></p> <center></center> <p style="text-align: center;">From the X-Pipe section the ARM S58 Midpipes transition back to the OEM muffler, which allows full use of the OEM exhaust valves.  <strong>This gives you the freedom to choose between open and closed exhaust flaps</strong>, controlling the volume your G80 M3/M4 produces.  Upgrade the look of your G8X to match the sound of your ARM S58 Midpipe by completing the kit with a set of <a href="https://www.armmotorsports.com/collections/g80-m3-s58/products/g80-exhaust-tips-m3-m4" title="S58 Exhaust Tips" target="_blank">ARM S58 Exhaust Tips</a>. <br><br></p> <div style="text-align: left;"><img style="float: none; display: block; margin-left: auto; margin-right: auto;" alt="S58 Midpipes ARM" src="https://cdn.shopify.com/s/files/1/0082/6687/4995/files/G8X-EXHAUST-TIPS-M3-M4-G82-G80_9_f4f11e67-7343-4f40-bee9-b1b70f1eb1c2_1024x1024.jpg?v=1693337825"></div> <p style="text-align: center;"><br><br>The ARM S58 Midpipes will secure to the <strong>exhaust hanger on the driver's side</strong> using a standard exhaust hanger prong.  It is secured to the passenger's side using the <strong>OEM style mounting bracket</strong>.  These help the exhaust from jostling around during aggressive driving.<br><br></p> <div style="text-align: center;"><img src="https://cdn.shopify.com/s/files/1/0082/6687/4995/files/Drivers_Side_Exhaust_Hanger_1024x1024.png?v=1723830965" alt="" style="float: none;"></div> <div style="text-align: left;"><br></div> <h1 style="text-align: center;">ARM S58 CROSSOVER PIPE</h1> <div style="text-align: center;"><img src="https://cdn.shopify.com/s/files/1/0082/6687/4995/files/S58-CROSSOVER-PIPE_1024x1024.jpg?v=1723834518" alt="" style="float: none;"></div> <p style="text-align: center;"><br>The ARM S58 Crossover Pipe <strong>removes the extra casting material and sound deadening of the OEM S58 crossover pipe</strong>, allowing an increase in sound your S58 produces.  The G82 M4 in the video below is equipped with the ARM S58 Midpipe, S58 Crossover Pipe, and ARM S58 Downpipes, providing an increase in volume over the OEM setup.  Pairing the ARM S58 Midpipes with the ARM S58 Downpipes will increase the overall volume of your S58 significantly more than the ARM S58 Crossover Pipe alone.  <br><br></p> <h1 style="text-align: center;">AXLE BACK ADAPTERS<br> </h1> <p style="text-align: center;">The <strong>ARM S58 Axle Back Adapters</strong> are designed to reduce down at the end of the midpipe to fit most aftermarket axle back systems.
