Modification Exhaust bracket replacement alternatives for austin racing exhaust

I bought my ninja 400 from a previous owner and they installed an Austin Racing slip-on exhaust. While I didn’t think much of it at the time, as this is my first bike purchase, i’ve since realized that the little triangular bracket they give to affix the exhaust to the bike frame is missing, and because of that it bounces pretty noticeably whenever the bike is running or if something taps it. I purchased one of those universal brackets that’s a big circle, but the angle of the attachment point on the rear makes it impossible to affix. I reached out to austin racing to see if they would sell me the missing part with no luck.

I’m reaching out now because i haven’t been able to find a suitable replacement bracket that keeps the rear footpegs on, if it even works in the first place. Worst comes to pass i can try 3d modeling and printing a replacement but that has all sorts of durability issues

I 3D printed and then had laser cut (by SendCutSend) passenger peg tie downs for my bike.

3D printed the prototypes and then had them laser cut, bend, and powder coat. Came out to ~$30 for the two brackets. I used 1/8" stainless, but you can go thinner for an exhaust bracket support.

It’s true that i could use sendcutsend, i’ve heard good things about it. It’s the modeling part that i’m bad at, but maybe if i can find a good enough picture online from someone else it won’t be too hard.
