Re: Exhaust Manifold to Tailpipe gasket
Seems like you made a simple job difficult for no good reason. Wayne

Re: Exhaust Manifold to Tailpipe gasket

If your manifold and your exhaust pipe is NOS and perfect and the clamp is put on right side up then it should not leak and you won't need a gasket. A bead of gook is a good idea though. A lot of people don't have trouble with exhaust leaks. But if you are like a lot of us with worn or damaged manifold surfaces and repro exhaust pipes that are not perfect then you may have leaks. That is me. I think your idea of using a tin can has a couple of drawbacks. As mentioned already, rust and thickness of the metal will become a problem very quickly. Also, the manifold and pipe have different inside diameters so if you weld the seams together ahead of time the sleeve will not fit snugly. I think you will be making extra problems for yourself. My method that worked well was to get an exhaust pipe reducing adapter that fit snugly down into the header pipe and also up into the manifold. I took a length of small diameter glass fiber wood stove door gasket, and tied it into a loop that would fit snugly over the pipe adapter. I trimmed the upper section of the adapter so that only about 1/2" extended up into the manifold. Then all that was left to do was to slide the header pipe in place and clamp it tight. The gasket totally sealed off any leakage. Problem solved. |

Re: Exhaust Manifold to Tailpipe gasket
Great diagram and pictures.
There are thread discussions on correct assembly and placement of the clamp. I get more out of the discussions than I do from the negative feed back. And I have found that a small ball pean hammer helps to tap the properly assembled clamp so it seats. And i try to use a floor jack to hold the muffler in place. Frees up my hands so I can fumble with the clamp bolts. The replacement mufflers I find at the swap have needed reworking the flange with said ball pean hammer to get a better fit. Bob |

Re: Exhaust Manifold to Tailpipe gasket
Here is also a drawing of the clamp proper alignment. There are two different diameters, the pipe and the manifold. Both halves of the clamp must be aligned so that the larger diameter is on the top. If you get it wrong it won't clamp anything well.

I have been wondering what people think of the "improved" repro muffler clamp that is threaded on the engine side, obviating the need for nuts and supposedly making for an easier installation. |

Wireless plate im sure is one of those gimmick fixes. After someone gets stumped as to random misfires or no starts then discovers its a simple wire they probably thought "well i dont want that to happen again" thus eliminating the wire. That wire has been around for a very long time but like now its not something the average hardware store had - people probably tried the general hardware store wire to find it broke or too stiff in short time. We had to use the same high flex bunch of multistrant wire for our voltage sense wire for our welding robots, if you used the normal THHN stuff it would last about a month or two then break. of course hardly ever broke fully so certian welds/angles it would spaz out and burn hot as hell as it thought the voltage on the weld wire was zero. Im kind of indifferent on the muffler clamp - the origonal style has the merrits that you can get them back apart usually or at the least you can cut just the bolts off and reuse the clamp. now the new style would be much much easier to install im afraid it will be the wrath of modern manifold bolts that love to rust and snap off right at the manifold.

I was not aware that the muffler clamp has been reinvented. Originals have always worked fine for me. I personally don't imagine the one you describe would be any better, but I guess we will hear about it in due course.

Re: Exhaust Manifold to Tailpipe gasket
Yep that thin tin can will break down / melt in no time and lodge or hang out in the baffles

Re: Exhaust Manifold to Tailpipe gasket
I have been using that type of clamp for years. Fitting ANY clamp there is a PITA, what with the clutch pedal being so close. The ones threaded on one side are a little less painful ITA.

Re: Exhaust Manifold to Tailpipe gasket
I used the metal insert Mitch suggested works great no leaks no sealer no gasket.

Re: Exhaust Manifold to Tailpipe gasket
This diagram of how the clamp installs correctly will solve many problems. Thanks for postin

Re: Exhaust Manifold to Tailpipe gasket
No one mentioned this, but make sure the rear tail pipe hanger is loose and allows the whole works to slide back and forth and rotate. I remove it and suspend the tail pipe with wire until after the clamp is installed, all with a floor jack at the front of the muffler.

Re: Exhaust Manifold to Tailpipe gasket
I bought the gasket and chucked it into the junk box,just a waste of money!

Re: Exhaust Manifold to Tailpipe gasket
Nobody has mentioned to loosen the tail pipe bracket at the rear to help with the alignment. This allows for a forward and rotational movement of the pipe.
