Exhaust sound example of the Cobra Sport BMW 420D quad exit M4 style exhaust conversion manufactured by Cobra Sport Exhausts in Sheffield, UK. The 420D cosmetic exhaust upgrade has been specially designed to offer a slightly deeper exhaust tone overall but stays within 2dB of the original exhaust. This cosmetic exhaust completely changes the look of the 420D diesel offering a sporty and aggressive quad tip styling upgrade which takes inspiration from the BMW M4.
This performance exhaust is designed to fit 420D F32 (Coupe), F33 (Convertible) & F36 (Gran Coupe) with the M-Sport bodykit with the addition of the interchangeable aftermarket quad tip exit lower rear panel (available separately).
