RPM Performance – BMW M135i F40 GPF Back Exhaust System

Upgrade the sound and appearance of your BMW M135i F40 with the RPM Performance 3" GPF Back Exhaust System, designed and manufactured in the UK for improved exhaust flow, a deeper tone and a more aggressive rear-end appearance.

Manufactured from T304 stainless steel, the system features 3" (76mm) CNC mandrel-bent pipework throughout for smooth, unrestricted flow. Each system is professionally fabricated and TIG welded in-house for excellent fitment, strength and long-term corrosion resistance.

Improved Exhaust Sound

The factory M135i F40 exhaust is relatively subdued, particularly with the GPF in place. Our GPF back system has been developed to give the car a deeper, sportier and more noticeable exhaust note, while retaining the factory GPF and the rest of the original emissions system.

This is a non-valved exhaust system, meaning there is no exhaust valve to connect or control.

Twin 4" Exhaust Tips

The system is finished with twin 4" polished stainless steel exhaust tips, giving the rear of the M135i a much more purposeful appearance while maintaining an OEM-style fit.
