AWE Valved SwitchPath Axleback Exhaust for BMW F97 X3 M / F98 X4 M

The SwitchPath axleback gives the X3 M and X4 M a deeper, cleaner exhaust note while keeping the cabin quiet at cruise. AWE's patented 180 Technology cancels drone, and the valved muffler lets you go from calm to loud with the factory exhaust button.

What you get

• Valved SwitchPath muffler that keeps the factory valve operation, with no extra harnesses or extensions.
• 180 Technology drone cancellation for a composed tone on the highway.
• 3-inch T304L stainless steel, sourced in the U.S., with few bends for good flow.
• Starts at the factory cut point, so it pairs with the factory mid-section or an aftermarket mid pipe built to the same cut point.
• Tip choices: Chrome Silver or Diamond Black.

Good to know

• AWE positions this system as emissions compliant.
