A brand new exhaust to Top Gear's range, this exceptionally well crafted catback system for the BMW F10 523i is especially pleasing to the eye as well as to the ear, with a brilliant set of four chrome tailpipes that really make the car stand out. This kit is also ideal to get the sporty M5 look that really complements the 5 Series. Available at a special introductory price, we are extremely keen to get quality sound and video clips of this system and can reward this effort by our customers with a partial refund.
