BMW 335i Performance Exhaust by Dinan — Axleback Freeflow with Helmholtz Chamber, Black (2012–2016). It delivers a deeper, sportier tone while remaining composed in everyday use.

Purpose-built to reduce back pressure, this system produces gains of up to +6 hp and +5 lb-ft at 6600 RPM. A tuned Helmholtz chamber cuts low-RPM drone, and the factory computer-controlled exhaust valve is eliminated for consistent flow. Made from 100% 16-gauge 304 stainless steel with twin 3.5" ceramic black tips, it installs using the factory brackets and hangers for precise fitment.
