Those versions include, 4.5in Downpipe, 6in Downpipe, and 6in Catted Downpipe. The stock B58 downpipe comes from the factory with a catalyst that severely restricts exhaust flow, causing excessive backpressure with increased boost.  Upgrading your downpipe unlocks power, improves turbo spool, allows you to safely run stage 2+ tuning, all while increasing the sound of your B58-powered BMW. <br><br><img alt="" src="https://cdn.shopify.com/s/files/1/0082/6687/4995/files/4.5inDownpipe_600x600.png?v=1707935484" data-mce-fragment="1"><br><br></span></div> </div> <div style="text-align: center;"> <h1>B58 MIDPIPE UPGRADE</h1> </div> <div style="text-align: center;"> <span><span><span>The ARM M240i/340i/440i Midpipe significantly improves the sound of your B58, giving it the aggressive exhaust note you're looking for from a tuned B58-powered BMW.
