Default RV-6A Exhaust rubbing engine mount

I am looking for ideas because I know someone has been down this road before.

The exhaust on the right side of my 6A rubs against the engine mount. There is not much space to move it to the right because then the heat exchanger rubs against the exhaust. I have but heat blanket in place in the area where the exhaust runs along the right side of the cowl. I also get some rubbing of the left exhaust against the engine mount but there is a lot of free space that I can move it to the left.

My first suggestion is to read the instructions on how to post a picture and what size to make it.

Second.... The instructions call for the exhaust to be tied together just before the firewall.

With that done, if you find the exhaust hitting the motor mount, hose clamp a piece of curved aluminum to the motor mount to protect the mount from wear.

I can't tell from your pictures what system you're using but if it's Vetterman, take a look at the instructions and I think he gives some ideas on adjustment areas.
I used Vetterman system on my -6A and if it's any help to you, there are a few pictures of my installation at the link below that has been working for 300+ hours with no major issues:
