we made the BEST exhaust system for the M340/M440i

Test fitting our BRAND NEW RVNG 4” True Single Valved Quad Tip Exhaust for the BMW M340i and M440i. Designed from the ground up for maximum flow and performance, this system replaces the factory dual-path exhaust with a full 4-inch single pipe, dramatically reducing backpressure and unlocking the true sound of the B58.
