BMW Gen 1 B58 340i / 440i Rvng 3.25" Resonator Delete Midpipe

The Rvng performance midpipe replaces the factory midpipe and resonators on Gen 1 B58 BMW 340i and 440i models.

Why you need it

Removing the resonators gives the B58 a deeper, louder, more aggressive note while keeping the factory valved rear muffler, so you still get a quieter mode for cruising. Rvng chose 3.25" to balance flow with ground clearance and clean fitment.
