iJDMTOY 4-Pin Y-Splitter Harness for BMW Exhaust Valves — Overview

This is a simple 1-to-2 splitter harness for BMW electronic exhaust valves that use a 4-pin connector. It lets you run two valve actuators from one factory valve control plug without cutting into the car's wiring. For cars like the E90, E92, F30, F22, and G20, it makes sense when you're adding a second valved muffler or dual-valve exhaust setup and want to keep the install clean.

Pick this over a custom splice job if you want something reversible and you know your car already has the correct 4-pin valve wiring. The main thing to check before ordering is connector style and pin count, because not every BMW valved exhaust setup uses the same plug. Routing is usually straightforward, but you still want to secure the extra length away from heat and moving suspension parts. It will not add valve control features by itself - it only splits the factory signal to two valves.
