Exhaust leak - hard to explain :)
Hi guys, I just recently pulled my D&D exhaust apart to polish the header pipe (which i am very pleased to say has turned a beuatiful bronze now), and am now noticing an exhaust leak.
Now I am not sure on exact words for all the pipes, so stay with me. The leak is coming from where the header pipe (main large one piece) connects to the rear cylinder down tube (lshort pipe from the rear down to the long pipe). No matter how tight I tighten it, and believe me, i've layed the torque to her, it still seems to sputter out exhaust making a crappy little noise.
It almost looks like the pipes are different diameters, the down tube being smaller, or maybe I am just not locking them together properley before putting the pipe lock thing (pipe clamp?) back on. Any suggestions would be great. Thanks guys...

Uh oh, really? I feel like a dumbass, it must have disintegrated before I took the bike apart, I made sure to look for gaskets when dissasembling. I guess I will have to get one from somewhere.. Thanks for the info. Can I use a no name brand something in the right diameter or is it a specific cut?

be aware, that the gasket can be a real pain to get on. you gotta do it just right or else it will shred, and you'll have to buy more. I tried using stock gaskets to put my hindle pipes on. it was a disaster. eventually, I resorted to silicon high temp gasket sealer. used on dirtbikes alot. I had leaks that wouldn't go away. I slapped some on, got 2 automotive exhaust clamps(they are way stronger) and locked that sucker down as tightly as I could get it. that would be my advise after all this. when you're tightening it, if you can tighten it any more, it's not tight enough. might be wrong but it worked for me. no leaks for a long time.

you flip that and reverse it. the header slides into the midpipe. if you can get it on, the slide the gasket onto the header, then slide the midpipe over it. I couldn't even get it onto the header without messing it up. they are like tightly wrapped duct tape. once they scuff any edge, inside or outside of the gasket, it shreds away, and then forget it, you'll never make it fit.

Oh yeah, forgot which was male and which was female. Either way, it would seem easier to slide the gasket onto the male part and then force the whole thing into the female part. Wouldn't this prevent it from deforming when trying to get it into place?

sure. just make sure that the rim around the edge of the midpipe opening doesn't catch or scuff that gasket as you slide it in. it would be good to have just a little clearance around the gasket as you bring the pipes together. unfortunately, my hindles didn't give me any room for clearance. the diameter of the midpipe at the opening was exactly the same diameter as the gasket so as carefull as I was, every time I tried to ease the midpipe over the gasket, it would scuff, and then its ruined. so instead, I attached an extension pipe to the midpipe that was close to the actual size of the header opening. therefore eliminating the need for the stock gasket. squirted silicon sealant everywhere, and locked that sucker down.
