Description
Upgrade the exhaust flow and sound of your BMW G01 X3 M40i or G02 X4 M40i with the DCE Parts GPF/OPF Resonator Delete Midpipe. Designed specifically for the M40i platform, this stainless-steel midpipe replaces the factory resonator configuration to provide a more direct exhaust path, a deeper exhaust note, and improved throttle response.
The DCE Parts resonator-delete midpipe is designed to reduce the weight of the original exhaust system while improving exhaust flow characteristics. The result is a more responsive driving experience with a deeper and more pronounced exhaust tone.
Performance & Sound
By removing the factory resonator section, the DCE Parts midpipe provides a less restrictive exhaust configuration designed to improve exhaust flow.
The system is engineered to deliver:
- Improved throttle response
- Increased power potential in the lower and mid-range
- A deeper and more pronounced exhaust note
- Reduced weight compared with the OE exhaust system
- Improved exhaust flow characteristics
The resonator-delete design is particularly suited to drivers looking for a more aggressive exhaust character while retaining the rest of the vehicle's exhaust system.
Stainless Steel Construction
The midpipe is manufactured from stainless steel, providing a durable construction designed for long-term use and resistance to the demanding temperatures and conditions associated with the exhaust system.
Its lighter construction compared with the OE exhaust system also helps reduce exhaust-system weight.
