Product Description

The MBRP S45003CF is an Armor Pro Series axle-back exhaust for the 2017-2021 BMW M240i equipped with the 3.0L B58 inline-six. As an axle-back system, it replaces the factory muffler and rear section while retaining the factory mid-pipe for a straightforward bolt-on installation. Street Profile tuning delivers a deeper, more aggressive exhaust note than stock without crossing into antisocial territory -- louder on throttle, refined at cruise. The system is built from 3" T304 stainless steel tubing and exits through dual carbon fiber angle-cut tips, each featuring a woven carbon fiber outer wall and a mirror-polished T304 stainless inner sleeve for a race-inspired appearance that resists the elements.

Armor Pro is MBRP's most durable series, using T304 austenitic stainless steel throughout -- a material that cannot rust, making this system equally at home in salt-belt climates and dry-weather markets. Backed by MBRP's lifetime warranty. Note this system fits the 3.0L M240i only; 2.0L engine variants use a different exhaust configuration and part number.
