The document describes how exhaust systems are made, including the materials and parts used such as stainless steel, cast iron, carbon steel, and fiber. The key processes involved are metal forming to shape flat sheet metal parts like mufflers through bending and rolling, and metal forging to shape round parts like pipes. The conclusion notes that stainless steel is commonly used due to its strength, durability and ability to handle high heat, making it a reasonably priced material for exhaust systems.

2. Materials And Parts
• Stainless Steel
• Cast Iron
• Carbon Steel
• Mild Steel
• Titanium
• Fiber
Exhaust Manifold And Gasket
Pipe And Muffler
Silencer

3. Process
Metal Forming
• Process of shaping flat sheet
metal parts without additional
materials or removing
materials. Eg.Bending and
Rolling. (Muffler)
Metal Forging
• Process of shaping round
metal parts without additional
materials or removing
materials. Eg.Bending and
Rolling. (Pipe)

5. Conclusion
• The exhaust system handles a lot of heat.So the exhaust
system must be strong and durable.For this reason
,stainless steel usually the material of choice as the price
is reasonable for its performance.
