Unlock the full character of your B58-powered M140i with the Xforce Varex Cat-Back Exhaust System. Designed as a direct bolt-on upgrade, this system transforms both sound and performance, giving you that classic straight-six growl on demand – with the ability to quiet it down whenever you need to.
The exhaust bolts straight onto the factory downpipe and uses twin 2.5” mandrel-bent pipes through the centre, offering excellent flow and ground clearance. These merge into a single 3” section feeding the Varex variable-valve muffler. Open the valve and the M140i comes alive with a deep, aggressive tone; close it, and it drops back to a subtle, refined note ideal for everyday driving.
Constructed from brushed 304 stainless steel, the system is built for long-term durability and a premium finish. The twin 4” polished tips complete the look at the rear, giving the M140i the presence it deserves.
Whether you’re after a quiet OEM-like drive or a loud, performance-focused soundtrack, this system adapts instantly to suit your mood.
