If your muffler is still intact you should be able to keep bending it until you get it to a point where it works. I usually take 4 or 5 tries at it before I get the muffler where I want it. A poo-poo pipe will need adjusted also. There is no such thing as "one size fits all" with these bikes! Good luck!

If you need to put a slight bend in your stock exhaust, I will give you a great tip on how to hold it down when you bend it.
Use an old piece of steel plate, channel Iron, anything you have laying around. Drill the hole pattern that fits your muffler in it. Bolt it down solid with a couple 6 mm or 1/4" bolts. Clamp that in the vise and bend away, That way you can give it a little bend without it pulling out if the vise.

Thanks Fin fan where did you get that kick _ss helment and goggles
That's not me. It is the "Gyro-Captain" from the second Mad Max movie.

I generally clamp the flange from the muffler assembly in my vise and use that to hold one end still while I heat the pipe and try to shape it.

Good idea, John. I put two 1/4" bolts in the vice, really tightened it and that worked too.


Beetle,
You can weld, (solder) copper to steel. If you know anyone in the air conditioning trade they use a product called, Silv-Aloy. That's a brand name, there are others. It is a high temperature solder alloy used in refrigeration piping. It is a type of silver solder that takes high heat to use and some practice to master. You'll need an oxy-acetylene torch or one called a Turbo-Torch to achieve enough heat to flow the stuff and it requires a special flux. A good air conditioning guy will have some on his service truck and if you offer him a beer he might do that soldering job for you. Plumbers don't typically use it but air conditioning / refrigeration people do. Good luck.

they sell a muffler adapter(it looks like a 1" thick gasket made out of aluminum). you could make one yourself. on mine im going to use a 1/2" gasket to move muffler away from my peddals and the muffler will tuck right next to frame.

Beetle,
That first picture threw me. When I looked at it I thought, "Wow, that's some exhaust pipe!" The I realized what I was looking at. It's a p***er to get old and loose your eyesight.

where do you order this 1" exhaust adapter. I need to move out about a 1/2", but it could work also. Thanks in advance....

I have ran into a similar issue with one of my builds and ended up cutting the muffler, so I now have a very loud bike. Does anyone sell shorter mufflers?

Cabinfever1977 said " they sell about a 1" aluminum adaptor between the muffler and manafold" I have been looking for this item for some time now, and can not find anyone that sells it...
could someone please send me to the right place to buy this item? Thanks, Mackie4

Beetle Juice, you are scaring me my friend. I'm picking up two Schwinn Landmarks this coming Saturday morning and already have the motors sitting in the garage. If I understand this paragraph, you had to modify the mufflers to fit the Landmark? I was hoping for an easy build for my first two builds. Oh well, I guess ya gotta learn the hard way first in order to appreciate the easy way.

the muffler does fit on my schwinn del mar , which is the same as the landmark i think.
and it need no modification or anything and im using just a thin regular gasket too.
I did have to tilt my motor til the muffler fit tight up against the frame and strapped it to the frame. my motor is raised a few inches on the frame cause i have a cent clutch and pullstart and need the peddals to clear the sides of the engine. i also changed the peddles to ones with shorter crank arms.

i would guess that if u have a reg engine and hav it low on the frame that the fat part of the muffler should be below the frame(u might have to bend the muffler pipe slightly) but i dont know cause mine is mounted higher.

hi im not to sure if this will help but if u have one of those square mufflers (commonly found part on weed eaters) i used it to adapt to the mount. i bought a steel plate drilled two holes identical to the mufflers two swrews holding it and and welded that onto my bike frame works fine and oh a spring or turnbuckle for extra pressure its madd only problem is mottor got fed up byond reapir...
