Exhaust Leak? Sato 9er style

So I suck at life, I know it, most of you who have read anything I've posted know it as well...I'm not too mechanically inclined and generally afraid of messing with anything as I fear I will break it in the process.

I slapped my Sato's onto my 9er and now have a lovely rattle eminating form the left canister (I think, reverberates only at 4k and 9k). May be the heatshield which should be easy enough to fix, but if it is an exhaust leak, here's my question - I didn't slap any sort of tape on any sort of piece when I joined the header pipe to the canister in their holy union...should I have? Can you overtighten the cramps that cinch it on there? In other words, can I go out to the shop and cinch it down and assume it will be fixed, or should I take the sucker off and begin a new. I didn't tighten everything as much as I could have, I was under the impression I could overwhelm the metal with my massive strength!!!

As always, any help from my favorite community is much appreciated.

So the heat shield was a bit lose, I didn't get up to much speed after repairing it during lunch, so I'll need to confirm that's the only issue. Anyone care to opine on the proper way to cinch up these slip-ons?

Take the heat shields off, really no need for them and the Sato ones are ugly anyways.

I was a bit hesitant at first with my Sato's, but in two years I've yet to even come close to burning myself.

You can use some High temp RTV for the joints, look for the Copper colored tube used for exhaust gaskets. Recheck your clamps at the joints after a couple heat cycles for tightness. Should take care of any leaks if you have em.

Sound like good advice, thank you!

While you are at it, check the heat shields for hairline cracks at the mounting holes. I was having the same issue with the noise in the same RPM range as you. I went through pretty much the same steps as you are, but it still did not fix it.
Then I took the shields off and did a very close visual inspection and found hairline cracks on both Ti shields where they fasten to the pipe. While they were off, I decided I liked the look without the shields and did not put them back on.

Noise gone.

Recurring theme here, sounds like the heat shields need to go. Thanks.
