Exhaust Manifold to Tailpipe gasket
Show of hands.
How many of you out there in "A" land have had a hard time lining up and holding that skinny copper and asbestos gasket while attempting to get the clamp around all three parts and slip the nut on the bolt of the exhaust manifold to tailpipe clamp? Well, sitting here in the garage listening to the rain dump on the roof, I think I have a solution to this problem. The "indoor folk" have been doing the baking of sweet goods and whatnot and have left me to remove the detritus and while doing this I have come across what I feel to be the perfect solution. In picture one, we see the antagonizer of this project. Picture two shows the can used. Now you may use whatever you have laying around that is close to the size needed unless you have a tubing maker thingamajig. Picture three shows cleaned and sliced. Picture four shows the gasket around the can for size and fitment. Picture five shows the finished welding of the can. Now since I have a resistance solder machine this was a piece of cake for me since it localizes the soldering of the part, but I suspect that anyone owning a small modeling torch or a fine tip for your O/A torch could do this as well. The joint shouldn't really need to be soldered, but to keep the can diameter the same from end to end I would think it should be fastened in some fashion, perhaps a pop rivet on each end would do the trick. Now since it is still raining outside and I am a dry weather mechanic, I won't be fitting or installing this today, but if you like what I have done so far, maybe I will take pictures of how it fits at installation. Since I am not totally sure how far the can will fit into reach part I have held off soldering the gasket onto the can, but I am thinking that because I want a real good seal, and the copper does touch the can I may just get a test fit for can distance and solder the gasket to the can after pre-fitting.

Re: Exhaust Manifold to Tailpipe gasket
Before I installed my Aries I just added a smear of muffler cement to my old header pipe and drove of into the sunset, worked for me.

Re: Exhaust Manifold to Tailpipe gasket
i didnt use any gasket as per stock and it sealed right up... i was able to hold it with one hand and put the clamp together with the other. Floor jack holding it up helps.
It also really helps to use a small hammer to tap the clamp tighter before tightening the bolts - it really helps it pinch the joint together without relying and possibly cracking the cast exhaust clamp.

Re: Exhaust Manifold to Tailpipe gasket
I agree with everyone that doesn't use a copper gasket just use a beed of muffler cement
It gives you a lot better seal Sent from my iPhone using Tapatalk

Re: Exhaust Manifold to Tailpipe gasket
I just did mine this weekend. Permatex copper gasket sealant with some new nuts and bolts and worked just fine!

Re: Exhaust Manifold to Tailpipe gasket
I know everyone talks helpfully about using a floor jack underneath it, but that has never worked really well for me. The tube between muffler and manifold is situated at an angle and not really perpendicular to a horizontal plane.

Re: Exhaust Manifold to Tailpipe gasket
Hey thanks for all your opinions.
Ya know, I thought you didn't need any input from me as it seems you all know it all, and all the responses just confirmed it. It was Real, and Fun, just not real fun. |

Re: Exhaust Manifold to Tailpipe gasket
Hmm after having to make a emergency exhaust pipe fix on my s10 with a cut up soup can and bailing wire that repair only lasted a year before the can turned to rust chunks/dust... I would not put a can inside to clog up the muffler/rattle around...

Re: Exhaust Manifold to Tailpipe gasket
There was not.
Adding a gasket just fouls up the fit for the muffler clamp. The gasket goes in the category of repro fixes to problems that don't exist -- until you add it. Like distributor wireless plates!

Re: Exhaust Manifold to Tailpipe gasket
ericr, I put a 6" piece of 2"X 6" with a couple 1" X 's about 2" apart tacked to the top of the 2 X 6 and put this on top of the floor jack. It rocked enough to take care of the angle and kept the pipe from moving.

Re: Exhaust Manifold to Tailpipe gasket
I typically have used a small scissor jack (gleaned from a long ago Honda), and place it under the forward most edge of the muffler itself (not the pipe). The scissor jack offers a little more precise lift than does the typical floor jack. I always put a piece of lumber between the jack and the muffler, just to protect things a bit.

Re: Exhaust Manifold to Tailpipe gasket
Quote:
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.

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
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
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.
