Dinan D660-0081 Resonator Delete Kit for BMW - 2018-2023 M5

The Dinan D660-0081 Resonator Delete Kit transforms the exhaust note of your 2018-2023 BMW M5 (F90) by eliminating the restrictive factory resonator, delivering a more aggressive, louder exhaust tone with smoother and fuller sound characteristics. This performance upgrade enhances the naturally aspirated V8 soundtrack without sacrificing refinement or introducing unwanted drone.

Key Features:

• Premium 304 stainless steel construction with brushed finish for corrosion resistance and durability
• 3.25-inch (83mm) diameter tubing replaces factory hydro-formed piping for improved exhaust flow
• Mandrel-bent X-pipe crossover design promotes balanced exhaust flow with minimal restriction
• Deletes the mid-pipe resonator located between the catalytic converters and rear muffler
• Direct bolt-on installation with all necessary mounting hardware included
• No cutting, welding, or modifications required for installation

Engineered specifically for the F90 M5, this resonator delete kit maintains proper exhaust system fitment while unleashing a more visceral exhaust note that better complements the twin-turbocharged 4.4L V8 engine. The mandrel-bent construction ensures smooth internal surfaces for optimal exhaust gas velocity and scavenging. Backed by Dinan's reputation for precision-engineered BMW performance upgrades.
