replace a rusty exhaust flange connector on a catalytic converter where it connects to the exhaust manifold. This will save replacing the entire catalytic converter as in this application the end of the pipe is flaired and/or in some applications the flange is spot welded to the end of the pipe.
Step 1: 1 Parts needed, TWO exhaust flanges for the proper size pipe. (example #240880 EXHAUST PIPE FLANGES JC Whitney .com) 2 small Nuts and 2 small Bolts (sized by holes drilled later)
Step 2: Tools needed; hacksaw or powered cutter wheel etc.; drill and bits
Step 3: Cut flanges as indicated
Step 4: Place one flange over the other and drill holes as indicated.
Step 5: *** NOTE*** Make sure that the pipe and manifold on your vehicle are cool enough to work on.
Step 6: Cutoff/remove the old flange from the pipe.
Step 7: Install one flange over the pipe and then slide the other half over the pipe.
Step 8: Align the flanges and secure together with nuts and bolts through the drilled holes.
Step 9: Slide the flange into place and secure to exhaust manifold.
Step 10: For broken/corroded studs bolts on exhaust manifold use (Example) 470112 CLAMP-A-STUD W/O HEAT RISER... see JC Whitney.com
