Before beginning installation, read and make sure you understand all instructions, and have
necessary equipment at hand.
Before working on the vehicle, make sure that it is well supported by jack stands or ramps of sufficient load
capacity for the weight of the vehicle. NEVER work on any vehicle which is supported only by its service
jack.
These extensions are designed to connect Pacesetter headers part number 70-2242 to original muffler and
tailpipes. They may not work with other headers.
1. Disconnect battery
2. Vehicle should be on lift (preferred) or on jack stands or ramps, and header installation complete.
3. Bolt one first extension (211321) to each second extension (211322 & 211323). It is advisable to use a
high temperature, O2 sensor safe gasket sealer such as Permatex Ultra-Copper both sides of gaskets.
4. Slide one band clamp over each header outlet with smaller diameter toward front. Slide driver side
extension assembly onto collector of driver side header and into band clamp. Slide passenger side
extension assembly onto collector of passenger side header and into band clamp. Snug clamps, but do not
tighten yet.
5. Align outlets of extension assemblies with exhaust pipe inlets and slide exhaust pipes forward onto
extension outlets.
6. Align pipes and tighten all clamps.
7. Install O2 sensors from original system and re-connect wires.
Remove vehicle from stands, reconnect battery. Start engine and check for exhaust leaks and rattles.
Listen or watch for clearance issues. Test drive.
It is recommended that all exhaust system clamps be re-torqued after the first hot-cold cycle, and
periodically thereafter.
Due to the lubricants used in the mandrel bending process, some smoke may be seen on initial
startup. This is normal and not harmful. It will disappear as the lubricant burns off.
