The McLaren 600LT features a flame-spitting, top-mounted exhaust. The exhaust was specifically designed to spit flames and therefore needs to be able to withstand extremely high temperatures. McLaren looked toward the aerospace industry in order to develop the correct material combination for their exhaust to withstand the intense thermal load by using a combination of titanium, Inconel, and other stainless alloys.

Increased driver engagement has been stated as one of McLaren’s selling points for the 600LT. The top-mounted exhaust improves the driving experience as the “singing” of the powertrain is now closer to the driver’s ears.

Being an exhaust with pipes facing outward, many people raise the concern of the engine filling up with water due to rain. The design team at McLaren has considered this and implemented slits and holes in the pipes that let the rainwater drain out.

Auto Trendy’s take:

McLaren has always been a perfectionistic company that innovates even the smallest of components. They make cars for enthusiasts and engineers alike. The exhaust been a not so small part of any car enthusiast’s vehicle. It is a component that automotive manufacturers take pride in developing and a competition point between manufacturers regarding the engineering of the “sexiest car noise.” It’s extremely exciting that McLaren took the time, effort, and resources to develop a material that would suit their exhaust vision perfectly.
