Construction and Design
High-performance exhaust headers for the Mazda RX7 are designed with both functionality and aesthetics in mind. Key features include:
Material: Common materials include stainless steel and mild steel, chosen for their durability and resistance to heat.
Tube Configuration: Performance headers often utilize larger diameter tubing and optimized routing to minimize bends and maximize flow.
Equal Length Design: Many high-performance headers utilize an equal length design to ensure that exhaust gases are expelled in a way that balances flow and maximizes scavenging.
Installation Process
Installing a high-performance exhaust header can be a rewarding project. Here’s a basic outline of the installation process:
Gather Necessary Tools: Acquire tools such as wrenches, sockets, gaskets, and possibly a lift or jack stands.
Disconnect Battery: Always begin by disconnecting the battery to avoid any electrical issues.
Remove Old Exhaust Header: Carefully detach the old parts while keeping track of any components that will be reused.
Clean the Surface: Thoroughly clean the mounting surface on the engine to ensure a proper seal with the new gasket.
Install New Header: Position the new header onto the engine, aligning it with the mounting holes, and secure it in place.
Reconnect Exhaust System: Reattach any necessary pipes and connections to complete the exhaust system.
Reconnect Battery: Finally, connect the battery and start the engine, checking for leaks and proper operation.
