    BMW’s only two-seat sport car, the Z4 was designed for the ultimate driving thrill. Fun, engaging and comfortable, the Z4 is meant to be constantly on the road, not in the garage. You can increase the Z4 thrill further with a custom exhaust system. Buy any of the exhausts available at CARiD and experience a burst of power from the engine, greater acceleration and more torque. What this means is that your Z4 will be able to cruise a lot faster, generate more power, go up hilly roads with more ease and overall feel like a much bigger car. CARiD has exhausts and exhaust parts for all Z4 models from Borla, Flowmaster, MagnaFlow, Onki, Gibson, Weapon-R, MBRP, Zunden and RBP. Each exhaust is custom designed to match each model’s specifications. Borla, MagnaFlow and Flowmaster cat back systems will reward you with the highest percentage of power gains. Expect anything between 7-10% from any of these.

    Bonus benefits of installing a custom exhaust include fuel economy, a great-sounding engine note and long-term savings. The custom exhaust enhances exhaust flow, boosting the performance of the turbocharged engine. In turn, the engine burns fuel more efficiently and you can see the effect as your fuel will be able to last a little longer and take you a little further. Your custom exhaust will generate a deeper and more power engine note, justly announcing the power within your Z4 turbo engines. The custom exhaust system will not need to be replaced, as it is built for long service. It comes in corrosion-free stainless steel and is joined together using advanced weld-on technology to prevent leaks. Your car deserves the royal treatment and feel-good benefits of a custom exhaust. Head to CARiD and pick an exhaust that is right for your car.
