Holley is proud to announce the release of Hooker BlackHeart Mini Cooper Cat-Back Exhaust Systems, which deliver gains of up to 5.3 horsepower and 6.5 foot-pounds of torque on the dyno. Developed specifically for 1.6L inline 4-cylinder base-model 2007-13 Mini Coopers and made entirely of strong, durable stainless steel, they provide optimum exhaust velocity and maximum ground clearance. These systems are 100% hand-welded, made of mandrel-bent 18-gauge 304 stainless steel with a 2.25-pipe for reduced in-cabin exhaust drone, come complete with all the necessary hardware, and utilize factory mounting points for factory-like fitment.
