: : : I clean the manifold and muffler flange areawith rough sandpaper to make sure it is clean.then take a jack and jack the muffler into the flange.Make sure that both flanges match at this time(very important).In stall clamp,make sure it fits both flanges well.Tighten,remove jack.No need for goop Henry did'nt use any.Happy A'un.
: : JD didn't say to use a small ball peen hammer to work the flange of the tail pipe to fit the exhaust manifold before installing the clamp. When installing the clamp tighten incrementally while gently tapping the clamp around it's perimeter. This will further help to seat the pipe with the flange. Also make sure the clamp is not upside down. Stranger things have happened. This advice from a fellow driving an A with the king of exhaust leaks... maybe I'll fix that tommorrow. Maybe....

I agree with the peening method for the flange.Would add that I have found the exhaust manifold flange surface to be worn.Uneven surfaces and or grooves are caused by a loose clamp allowing the exhaust pipe to swing.Generally, these surfaces can be restored by light grinding or filing, making sure to keep the proper angle and shape.By peening the exhaust pipe with a hammer and dolly, more stock can be added to the flange, allowing it to cover more of the manifold surface.This has worked for me....without the use of sealers and other things heretofore mentioned.In all, have fun with it!
