The exhaust gases from cylinders #1, #3, #5 and #7 travel through the left exhaust manifold and an exhaust crossover pipe to the right exhaust manifold, where they join the exhaust gases from cylinders #2, #4, #6 and #8 before entering the turbocharger. Flared flanges seal the joints between the exhaust manifolds and the crossover pipe.
Exhaust gases exiting the turbocharger travel through a single pipe to the muffler (see Figure 6-21). A pipe carries exhaust gases from the muffler to the outside air. Hangers positioned in several locations have isolators made of composite material to dampen the transmission of noise and vibration from the exhaust system to the vehicle body.
