any questions, contact our Technical Hotline at: 1-800-416-8628 , 7am - 5pm, Monday-Friday, Pacific Standard Time

1. With Edelbrock headers part #6570 installed, slip the left inlet adapter tube onto the left header collector.
2. Slip the Y-pipe assembly into place. The right side will slip directly onto the header collector, the left side slips over
the adapter tube that was installed in step 1.
3. Install T-bolt clamps as needed on header collector and on left inlet adapter. Position the clamps so the bolt is either
on the top or the side of the tubing for best ground clearance. The short adapter tube can be used, if needed, to attach
the vehicle’s exhaust system to the new Y-pipe assembly.
4. Be sure the hanger bar welded to the Y-pipe assembly is fully engaged into the insulator and the insulator is straight
and the attaching bolts are tight.
Note: If O2 sensors are to be used, supplied O2 bungs can be welded onto the Y-pipe where they are needed. Simply
mark the tube where you want the sensor, drill a 5/8” hole and weld the bung to the tube.
