Exhaust box internal baffle

[Arrow]

Dear Owners,

Recently I tried to syphon out the excess water from my rear muffler by putting flexible tubing up the exhaust pipe. When starting up after this the exhaust sound is now booming as if I had a hole in the system, which I don't. I used an endoscope to have a look at what damage I have done and can see a missing textured area on the inside endcap but the perforated pipe and wadding seems ok.

Does anyone know where I can find a detailed picture of the inside of a Walker fonos 21303 exhaust box, particularly any baffles and the backplate?

Thanks for your help.

Yours faithfully

Similar to this I imagine, no idea if you'll find this helpful or not

Thanks 1275, much appreciated.

I have seen similar videos on YouTube but I wanted to know the material of the back plate on the Fonos 21303 where the exhaust gases bounce off before going down the exit pipe as this is what I have damaged.

Thanks again for your time and effort.
