Exhaust Mounting Suggestions By renegadestang (Read 1,381 times)

So, I have a dilemma. I'm installing a new exhaust on my scoot (the old one finally fell/rattled apart, LOL). However the PO laid the bike down a couple of times, one of those times being on the exhaust, which broke off the lower mounting casting on the block. My question is, what would y'all suggest I do to go about mounting this so that it doesn't vibrate and break apart?







FWIW, this is the exhaust I'm putting on. I am aware I'll have to fab up some brackets.

I like those rims you got on yours

[redroush00]

Ive seen JB weld used. Even drilled and tapped...

[jct842]

not on the bottom of that engine.....I think jb will not hold because of the heat. I would try some threaded rod with some large washers on each side of the engine mount for the exhaust. It looks as if there may just enough left there if it is a flat surface or if you could get it flat that you could still use it. The largest dia you can get thru it along with a washer on each side followed but a nut on each side.

With out a mount the new exhaust will self destruct in short order/

Well, you have the top mounting point at least, IDK that it wouldn't be just fine with the one mount and where it meets the engine...

BUT if you decide to fab some brackets, I would make a triangle for the most support possible.

GOOD LUCK!

LOL, thanks. They're the stockers that came on it.

Thanks for the luck! And yea, I've spent some time in the offroad community, so I know that triangulation is key.

Ok, decided to try out the "metal weld" putty first and see how it does. Seems pretty tough. Anyway, what I'd like to see if anyone can help me with is which of these brackets is gonna work with my scoot.

If both will work, is one any better than the other? Thanks!

I would use the motor mount bolt for the top bar.

So are you saying not to use either of those bracket sets and to just use some flat stock?

[Alleyoop]

Yes, because the top bar now has to be longer. Many with the same problems use flat metal bars.

Here you can get a good idea of what you need to do. This one just happened to do it using the flat bar because of the different setup that a regular mounting hardware would not work.

Thank you!

Ok everybody! I think I've finally gotten this taken care of. So, I ended up hacking my old header pipe and the new header pipe and had them welded together. That way I had the shape of the old one to fit around the frame and such and the end of the new one so the muffler would bolt up. Used some cheap aluminum angle stock and rigged up some triangulation to secure the pipe and muffler. I think it looks pretty good, seems to hold pretty tight. Made a short trial run and it sounds much better than with the straight pipe. LOL!
