What's wrong with this muffler?

[mudski]

According to fleabay, stainless steel ain't any dearer than mild steel.
It's that ones that're purposely made for Patrol arent' available cheaper.
I wonder whether I can modify a standard stainless steel muffler of the same size to suit mine.

Of course you can. A muffler is just made at a generic size, and in and out orientation. Its the pipes on either side that matters.
