If you are experiencing pulsating brakes, grinding, or have ridges on your rotors, it’s time to consider replacements. These rotors are slotted to ensure optimum stopping power by allowing for better evacuation of heat and gases. Black zinc plating also ensures quality and great looks for a long time to come. When doing a brake job, be sure to inspect the calipers, pads and brake lines for signs of wear. We carry a wide variety of brake pads for the daily driver or for the performance motorist.

The catalytic converter is an emissions device that converts the exhaust gasses exiting the engine into a less toxic substance. This is achieved through the internal honeycomb monolith, washcoat, and the catalyst itself that commonly consists of a mix of precious metals. Unfortunately the catalytic converters do not last forever, and can be damaged if the engine is running too rich on fuel. If you're getting an oxygen sensor fault, and the sensor is ok, the likely cause is a failed catalytic converter. Relieve worry about an upcoming emissions test and replace your faulty or damaged catalytic converter.

Free ground shipping! These Supersprint metallic sport cats are for the Z4 M with Supersprint's own stepped headers. The piping is slightly oversized and the Supersprint sport cats are much freer-flowing than a traditional stock cat. With less restriction, less effort is required to move the exhaust gasses which will free up horsepower and torque. This cat section will only mount to the Supersprint full stepped headers (p/n 044001) and then to any section 2. These cats are built with O2 sensor bungs pre-installed after the cat if you wanted to extend your stock post-cat O2 sensors (however, special software may still be needed). Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price, Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long-lasting construction, and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preference. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation! This product modifies (but does not remove or defeat) emissions equipment. For this reason this product may not be CARB compliant, and therefore not emissions legal in some states. Consult local laws and regulations in your area. For more information on this product, feel free to contact our sales department.
