How much you p[lan on cutting it down? If you cut it to much it will get louder. I don't think you have to much to worry about, some of the packing might come out, but you won't totally ruin the muffler. If it were me, I'd find a pipe size that will match the inside diameter of the inner perferated one, if they don't have a size you could always cut a section of pipe and just tack it together to make the right sixe. This way after you cut the end off you can just stick that pipe in there to keep any material from coming out, then weld your exhaust system to that pipe.
Of course doing all that work is alot of time, last time I bought a thrush muffler it came in different sizes, and the biggest one I got was 20 bucks, so your probably better off just buying one, unless your bored and just want to do it for the hell of it.
