BMW Agency Performance Valved Stainless Steel Cat-back Exhaust - E90 / E92/93 M3
Bring the legendary S65 V8 to life with the Agency Performance Valved Stainless Steel Cat-back Exhaust. Designed for the E90 M3 and E92/93 M3, this system blends durability, sound control, and performance to unlock the full character of BMW’s high-revving naturally aspirated V8.
Crafted from premium T304 stainless steel, this cat-back delivers strength, corrosion resistance, and a perfect OEM-like fit. The valved system gives you full control of your sound: with the valves closed, enjoy a subtle, refined tone for cruising; with the valves open, unleash a raw, aggressive V8 roar that’s sharp, exotic, and race-inspired.
Engineered to improve exhaust flow, this system enhances throttle response, reduces weight compared to stock, and creates a dynamic exhaust experience that can be tailored to street or track driving.
