Description
(Exhaust Brace Included)
There’s nothing on the market quite like our 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.
With the valves open, you’ll experience an aggressive, deep exhaust note and faster turbo spool thanks to the unrestricted single path. Close the valves, and you get a refined, quieter tone for comfortable daily driving.
Hand-built from high-grade stainless steel and finished with precision TIG welds, this exhaust is built to handle serious power while looking as good as it sounds. The quad tip setup gives a clean OEM-plus appearance, while the 4-inch main pipe ensures your M340i or M440i breathes freely, whether stock or heavily modified.
