Unlock performance and sound with the Garage Whifbitz 3.5 inch stainless steel exhaust for the BMW M3 and M4 F8X platform. Designed for the S55 engine, this high quality valved cat-back style exhaust system delivers proven gains of around 12 bhp on a stock car based on wheel horsepower dyno results, while transforming the soundtrack of your BMW without the unwanted rasp. Ideal for BMW M3 F80 and BMW M4 F82 F83 owners seeking more power, deeper tone and premium looks with carbon tips.
- Proven performance - approximately 12 bhp gain on a stock S55 at the wheels
- Optimised flow - 2x 3 inch from the downpipes merging into a single 3.5 inch mid section, then splitting to the rear silencer
- Valved exhaust - retains the factory twin exhaust valves for intelligent sound control
- Drive mode integration - quiet in Efficient, aggressive in Sport and Sport Plus when valves open
- Single 3.5 inch midpipe - reduces S55 rasp and enhances a smooth, rich tone
- Ovalised mid section - maximised ground clearance for lowered and track focused cars
- Includes 4 carbon exhaust tips - premium finish that looks as good as it sounds
- Stainless steel construction - durability and performance focused design
- Also available in titanium if you want it super lightweight
This Garage Whifbitz system starts as twin 3 inch pipes at the downpipes, transitions to a single 3.5 inch ovalised midpipe for maximum underbody clearance, then splits to feed the large rear silencer. By retaining the two OEM style exhaust valves, you keep factory style valve control and the perfect dual character. Cruise quietly day to day, then open it up in Sport or Sport Plus for a louder, more engaging exhaust note when you want it.
On the S55 engine, the single 3.5 inch midpipe architecture helps tame the typical rasp while improving throttle response and flow. The result is a deeper, smoother tone with a refined edge and the power increase you expect from a performance exhaust for the BMW M3 and M4 F8X platform.
