| The rear section of the exhaust is a Meisterschaft Titanium setup consisting of dual mufflers and a protective shield. |
The Akrapovic mid-section and Meisterschaft rear section are both titanium for a serious reduction of weight. The two together trim over 50 pounds off compared to the stock exhaust system! There’s also a big power gain of over 20 hp.

| The rear tips of the Meisterschaft exhaust tucked in nicely with the rear diffuser. Another nice piece of BMW engineering is the rear bumper vent that can reduce aerodynamic drag and increase downforce by improving the effecitiveness of the rear diffuser. |

An increase in power needs to be matched by an increase in braking power and grip. Top-of-the-line Stop Tech Trophy big brakes kits are used front and rear for a properly balanced setup. The Stop Tech rotors are 380mm and 355mm front and rear as compared to the stock 360mm and 355mm respectively. The forged Stop Tech calipers are major upgrades going up to 6-piston on the front and 4-piston on the rear. The stock calipers are a 2-piston sliding design on the front and single piston sliding design on the rear. Stop Tech sizes the caliper pistons to retain proper hydraulic proportioning which is critcal. With multiple piston sizes available in small increments, Stop Tech does this better. With proper proportioning the kit is perfectly compatible with the factory ABS, brake proportioning and stability controls.

The wheels are upsized from the factory 18” setup. BMW offers an upsized wheels and tire package consisting of 19×8.5 and 19×9.5 wheels paired with 245/35 and 265/35 wheels from the factory. However, the Zebra goes even bigger by increasing the widths to 19×9 and 19×11 with 255/35 and 305/30 tires. The substantial increase in rear tire width is needed to match the big increase in power!
