CB125 exhaust compatibility

[Rimmy]

Can anyone shed some light on exhaust swappability for CB125s? I have a 1984 CB125s and I cut off the original pipe and have been playing with Emgo's for a while. Anyhow, with a reducer and some quality clamps I can't get a good seal. the small diameter makes it hard to find a pipe for. I'm thinking of going back to stock, but I've already junked the old muffler. Does anyone know if I can put one on from a previous year? I'm tired of not being out riding and want to quit messing around with this.

Not sure if it helps, but I got a reducer from autozone that fit on the end of my 125's pipe, which is actually a 100 pipe, so a bit smaller than stock. My reducers fit very snug on the reducer pipe and I haven't had issues. It looks like this:

The smaller end went on my pipe and the bigger end was what the reducer sat on.

Thanks for your reply. I have a reducer that is snug and some decent clamps, but it keeps rattling loose. I wonder if an exhaust shop can weld it all together for me.

I'm sure they can, or weld up something different. Wouldn't hurt to go in and just talk to them

I used these Honda muffler gaskets on my CB350 headers to connect to some aftermarket mufflers. They were about $10 each at the local Honda dealer.
