From there the ARM B9 S4 Downpipe has a <strong>massive 6.5" section</strong> to maximize exhaust flow straight off the turbo, which then transitions to a<strong> Y-section</strong>. <br><img alt="ARM B9 S4 S5 DOWNPIPE" src="https://cdn.shopify.com/s/files/1/0082/6687/4995/files/B9-S4-DOWNPIPE-10_9a3f0f26-a56a-420a-8cee-2707795d5faa_600x600.jpg?v=1724163495" style="float: none;"><br><br>The Y-section on the ARM B9 S4 Downpipe starts at a healthy 3.5", and then steps down to gradually to match the OEM midpipe flanges.  The midpipe flanges on the ARM B9 S4 Downpipe are precision cut and designed to <strong>match up to</strong> <strong>either the OEM B9 midpipes, or the ARM B9 Midpipes</strong>.  Pairing the ARM B9 3.0T Downpipe with the ARM B9 Midpipes creates an exotic and intoxicating exhaust note that will leave you grinning ear to ear.<br></p> <p><br><img src="https://cdn.shopify.com/s/files/1/0082/6687/4995/files/b9-s4-s5-downpipe-4_600x600.jpg?v=1722612634" style="float: none;"><br><br>The ARM B9 3.0T Downpipe comes with 2x midpipe gaskets and hardware for these flanges.<span><br></span></p> <h1 style="text-align: center;">IN THE BOX</h1> <div style="text-align: center;"> <span>• ARM 3.0T B9 Downpipe<br></span><span>• Midpipe Gaskets and Hardware</span><br><span></span><span></span> </div> <br> <h1 style="text-align: center;">FITMENT GUIDE</h1> </div> <div style="text-align: center;"><br></div> <div style="text-align: center;"> <table style="width: 100%; height: 176.344px;" class="appTable"> <tbody> <tr style="height: 19.5938px;"> <td style="width: 20.3639%; height: 19.5938px;" class="make"><strong>Make</strong></td> <td style="width: 26.1547%; height: 19.5938px;" class="model"><strong>Chassis</strong></td> <td style="width: 23.5431%; height: 19.5938px;" class="submodel"><strong>Model</strong></td> <td style="width: 24.8288%; height: 19.5938px;" class="engine"><strong>Engine</strong></td> </tr> <tr style="height: 19.5938px;"> <td style="width: 20.3639%; height: 19.5938px;" class="make">AUDI<br> </td> <td style="width: 26.1547%; height: 19.5938px;" class="model">B9<br> </td> <td style="width: 23.5431%; height: 19.5938px;" class="submodel">S4<br> </td> <td style="width: 24.8288%; height: 19.5938px;" class="engine">3.0T<br> </td> </tr> <tr> <td style="width: 21.2177%;">AUDI</td> <td style="width: 27.3063%;">B9.5</td> <td style="width: 24.5387%;">S4</td> <td style="width: 25.8303%;">3.0T</td> </tr> <tr style="height: 19.5938px;"> <td style="width: 20.3639%; height: 19.5938px;" class="make">AUDI<br> </td> <td style="width: 26.1547%; height: 19.5938px;" class="model">B9</td> <td style="width: 23.5431%; height: 19.5938px;" class="submodel">S5 Coupe</td> <td style="width: 24.8288%; height: 19.5938px;" class="engine">3.0T<br> </td> </tr> <tr> <td style="width: 21.2177%;">AUDI</td> <td style="width: 27.3063%;">B9</td> <td style="width: 24.5387%;">S5 Sportback</td> <td style="width: 25.8303%;">3.0T</td> </tr> <tr> <td style="width: 21.2177%;">AUDI</td> <td style="width: 27.3063%;">B9.5</td> <td style="width: 24.5387%;">S5 Coupe</td> <td style="width: 25.8303%;">3.0T</td> </tr> <tr> <td style="width: 21.2177%;">AUDI</td> <td style="width: 27.3063%;">B9.5</td> <td style="width: 24.5387%;">S5 Sportback</td> <td style="width: 25.8303%;">3.0T</td> </tr> </tbody> </table>  </div> <div style="text-align: center;"> <div> <h1>ARM MOTORSPORTS LIFETIME WARRANTY<br> </h1> </div> <div>Every ARM Motorsports product is backed by a lifetime warranty which is automatically issued at the time of purchase.
