DCE BMW G01 X3 & G02 X4 M40i OPF/GPF Resonator Delete Midpipe

The DCE BMW G01 X3 & G02 X4 M40i OPF/GPF Resonator Delete Midpipe is engineered to unlock a more engaging driving experience from your B58-powered M40i. Designed as a direct replacement for the factory OPF/GPF resonated midpipe, this high-quality stainless-steel upgrade reduces flow restriction, improves exhaust tone, and enhances responsiveness — all while maintaining full compatibility with both left-hand drive and right-hand drive vehicles.

By removing the restrictive factory resonator, this midpipe delivers a noticeably deeper, sportier exhaust note, allowing the signature B58 sound to come through with greater clarity. Drivers will also benefit from improved throttle response and increased performance throughout the lower and mid-range RPMs, thanks to the more efficient exhaust flow and weight reduction over the OE system.

Whether you're upgrading for sound, performance, or both, the DCE resonator delete midpipe provides a high-quality, durable, and cost-effective solution, crafted from premium stainless steel for long-lasting reliability.
