BMW F30 / F22 / F36 / F32 Valved Sport Exhaust System (Axleback) F chassis

Description

T304 stainless steel valved axle-back exhaust system for BMW F-Series applications, featuring electronic valves and a cast Y-pipe.

Overview

The Version 2 Valvetronic Designs F-Chassis Valved Exhaust introduces an updated valve design, relocated hangers, revised muffler internals and a cast Y-pipe for improved flow and a more refined closed-valve tone. It can be paired with the OEM mid-pipe or compatible aftermarket mid-pipes using factory dimensions.

Why It Works

• Valves Closed: Near-stock sound for quieter driving.
• Drive Mode Integration: Compatible with BMW factory valve-control functionality where applicable.
