Restrictive factory emissions equipment and petrol particulate filters severely choke the exhaust note of the mighty S68 engine. Reclaim the authentic V8 roar of your hybrid M5 by swapping out the dense factory piping for high-flow Exhaust Downpipes, dramatically improving gas velocity and turbo spool. Transform the acoustic presence of your Saloon or Touring with a premium GPF-Back Exhaust system for a refined yet aggressive tone. For dedicated motorsport applications, utilizing GPF deletes will remove the restrictive filter media entirely, allowing the 727bhp powertrain to exhale without limitation.
