Investment casting in the exhaust
The exhaust system of a vehicle filters the combustion exhaust gases of the engine and dampens the noise emissions. The tailpipe trim forms the end of the exhaust system and is attached to the exhaust system after the muffler. It can often impress with visually individual shapes that round off the aesthetics of the vehicle.
A conventional material for exhaust trims is stainless steel, as the exhaust system is part of the exhaust stream, which must withstand hot combustion gases. For this reason, high-quality, durable and weight-saving exhaust systems are often made of aluminium or titanium alloys. In addition to the weight reduction, the positive effect on torque and vehicle performance as well as the sound formation should also be mentioned.
The tailpipe trim of the Porsche Cayenne impresses with its modern design and was installed in the Cayenne as an add-on as part of the "Porsche Exclusive" individualisation programme. During realisation, special attention had to be paid to the corrosion resistance of the alloy and the high temperatures. In collaboration, not only was an investment casting developed, but also an assembly ready for series production, which skilfully underlines the sporty design of the Porsche Cayenne.
