BMW X4M F98 J Pipe Control Exhaust System

Enhance sound and performance on your 2018-2025 BMW X4M F98 with a J Pipe Control Exhaust System available in Grade 5 Titanium, Stainless Steel 304, or Gold Plated Stainless Steel, engineered to improve exhaust flow while delivering on-demand sound control.

The system combines a J Pipe mid-section with a valved Control Exhaust, optimizing exhaust flow through the mid-pipe while reducing restriction throughout the system. This allows exhaust gases from the 3.0-liter twin-turbo S58 inline-six engine to exit more efficiently, improving exhaust flow while producing a deeper and more aggressive performance exhaust tone.

The Control system features electronically controlled dual-mode valves, allowing you to switch instantly between refined cruising and aggressive performance sound. With the valves closed, exhaust gases pass through the mufflers for quieter driving, while opening the valves provides a freer exhaust path that unleashes a louder and more pronounced performance exhaust note.

Constructed from Grade 5 Titanium, Stainless Steel 304, or Gold Plated Stainless Steel using TIG welded joints and mandrel-bent tubing, the system ensures smooth exhaust flow, precise fitment, and long-term durability under high heat and load. The Grade 5 Titanium option reduces overall weight for performance-focused builds, while Stainless Steel 304 provides excellent corrosion resistance and structural strength. The Gold Plated Stainless Steel option adds enhanced thermal resistance with a distinctive premium finish.

Designed as a direct bolt-on upgrade using factory mounting points, this exhaust installs without cutting or welding and integrates seamlessly with the OEM exhaust layout.
