2025+ BMW M5 G90 / G99 S68 Valved Catback Exhaust

Transform the sound of your 2025+ BMW M5 G90 Sedan or G99 M5 Touring with the 3StripeDaily S68 Valved Catback Exhaust System. Designed specifically for the latest-generation M5, this system gives the S68 twin-turbo V8 a deeper, more aggressive exhaust note while retaining valve control for a more refined driving experience when desired.

The valved catback design lets you change the character of the M5 depending on how you drive it. Keep the valves closed for a more subdued exhaust note during cruising and daily driving, then open the valves when you want to hear more of the S68 V8.

Designed as a complete catback upgrade, the system replaces the exhaust components behind the factory catalytic-converter section. It delivers a more exciting sound and performance-inspired appearance without requiring replacement of the factory catalytic converters.
