BMW X3 M40i Performance Exhaust - Dinan - Axleback Exhaust System - Polished (2019-2025). This valved system brings a deeper, sportier voice while preserving comfort.
Built from 100% T304 stainless and TIG-welded, this free-flow axleback with a Helmholtz-tuned muffler helps curb drone and enrich the signature Dinan rumble. Factory valve control is retained: quiet when closed, more assertive when open. Quad, double-walled polished tips with laser-engraved logos complete the package, and it bolts on using stock mounts. Compatible with pre-LCI and LCI G01 X3 M40i models.
