Garage Whifbitz 3.5" titanium exhaust for the BMW M4 & M3 F8X.
Gains of around 12bhp on a stock car, (dyno graph shows power at the wheels).
Made from super lightweight titanium our full exhaust weighs in at only 15kg! Thats from the downpipes to the back of the car with a large rear silencer fitted to keep the noise levels down.
Our exhaust is 2x 3" where it meets the downpipes converges into a 3.5" single pipe mid section and splits into 2 pipes to meet up with the large rear silencer which retains the 2 exhaust valves as per the OEM exhaust. So when you're driving in efficient mode its quiet and when in sport/sport + mode with the exhaust valves open its loud.
The single midpipe section is ovalised for maximum ground clearance and the single 3.5" pipe helps to keep the raspy noise you can get from the S55 engine under control.
Also available in stainless steel.
Downpipes and midpipes are available seperately if you want to retain your OEM rear silencer.
