Milltek Sport Cat-Back Exhaust System – BMW M140i F20/F21 LCI

Upgrade the sound, appearance and driving character of your BMW M140i with a Milltek Sport Cat-Back Exhaust System — a premium stainless steel exhaust upgrade designed for the 3.0L turbo B58 platform.

This listing is designed to cover multiple Milltek Sport cat-back configurations for the BMW M140i F20/F21 LCI non-OPF models, allowing customers to select the preferred sound level and tailpipe finish before ordering.

Designed for the BMW M140i

The BMW M140i is one of the most popular modern performance hatchbacks, combining the B58 turbocharged six-cylinder engine with a compact rear-wheel-drive platform.

The factory exhaust is designed with refinement in mind, while the Milltek Sport cat-back system helps give the M140i a deeper, more engaging and more performance-focused exhaust character.

Choose Your System Configuration

This product may be available in multiple configurations depending on the selected variant.

Resonated / Quieter

The resonated system is the more refined option.

It is ideal for customers who want a deeper and sportier exhaust note while keeping the vehicle comfortable for daily driving, commuting and longer trips.

Non-Resonated Race / Louder

The non-resonated race system is the louder and more aggressive option.

It is suited to customers who want a stronger exhaust note, sharper sound and more presence from the B58 platform.

Choose Your Tailpipe Finish

This Milltek Sport system may be available with multiple trim finishes depending on the selected variant.

Available trim options may include:

• Polished GT-90 trims
• Cerakote Black GT-90 trims
• Titanium GT-90 trims
• Burnt Titanium GT-90 trims
• Carbon Jet-90 trims

Final available trim options will depend on the selected Milltek system configuration and SKU.
