Align 600 metallic rattle

[TimR]

Don't know if you managed to figure out what was rattling in your heli Jason, but after my 'hard landing', my muffler has a loud rattle! Mine is the Align high performance one, and it looks like something has come apart internally - not uncommon apparently, so maybe it wasn't the shock that broke it?

Any ideas on what I might replace it with?

I changed a few things at the same time, but think it was the starter one way bearing. I use the Curtis Muscle pipe and the sab exhaust. The cheapest I think you will find are the Align ones which work fine.
