The primary role of an exhaust system on your average vehicle is an attempt to reduce some of the toxicity of exhaust fumes. In achieving this, there inevitably is an element of restrictiveness which indicates operating inefficiencies. For track cars, exhausts designed and fabricated to be the least restrictive perform better. Typically, exhausts are manufactured from cast iron, nickel alloy or steel. Competition exhausts will likely be made from stainless steel or even titanium; the latter being equally as strong yet just over half the weight of the former.
