BMW M135i – Rear Valved Exhaust Upgrade at MIJ Exhaust! 🔥

This BMW M135i rolled into MIJ Exhaust for a rear valved exhaust system upgrade, giving it the perfect balance between everyday refinement and all-out performance sound. 
The valved setup allows the driver to control the volume and aggression on demand — quiet and composed when cruising, loud and purposeful when pushing on.

With the valve open, the M135i delivers a deeper, more aggressive tone with crisp pops and a sharper edge that truly complements its turbocharged performance. Closed, it remains smooth and subtle, ideal for daily driving. 🎶

A smart, driver-focused upgrade that enhances sound, presence, and excitement – unlocking the full character of this performance hatch. 🔥
