AWE Non-Resonated Performance Mid Pipes for BMW F97 X3 M / F98 X4 M

These mid pipes replace the factory mid-section on the S58 X3 M and X4 M with a straight-through pair of 3-inch pipes and no resonators. A custom X-pipe sits in the middle to sharpen and deepen the S58 tone, and with AWE's SwitchPath axleback the result is a full, smooth note without rasp.

What you get

• Two 3-inch non-resonated pipes that start just behind the factory secondary catalysts.
• Built-in X-pipe tuned for the S58 sound.
• Works with your existing rear. Compatible with the factory axleback, the AWE axleback, or any system that meets the OEM cut point.
• Emissions compliant in all 50 states.
• Built in-house by AWE, backed by its no check engine light and fitment guarantees and a lifetime warranty.
