Extension Pipe
1. Cut O.E.M. exhaust pipe approximately 1/2” to 3/4” in front of the catalytic.
2. Bolt catalytic back into vehicle with front in original location.
3. Install T.E.S. pipe over catalytic inlet and bolt to T.E.S. manifold using donut gaskets provided.
4. With everything in place, tack weld T.E.S. to catalytic.
Note: Tig welding is desirable but gas welding can be used.
5. After tack welding, remove assembly and complete weld.
6. Re-install assembly and tighten all bolts.
7. Check all wires and lines for adequate clearance.
FINAL INSPECTION
1. Check all hydraulic, vacuum, and fuel lines to ensure there is adequate clearance to T.E.S. components.
2. Re-connect battery.
3. At this point, it is a good idea to look everything over and make sure nothing was missed in assembly.
4. Start vehicle and bring up to normal operating temperature. Check for possible leaks.
5. Turn engine off and let cool. Tighten all bolts again.
