Pretty sure most places offer the dump, although best muffs give great service from memory.
The cat position is determined by the location of the two stock o2 sensors. So it would be easiest to put it somewhere at the end of the dump, otherwise you'll be looking to disable a cel code as well as looking legal etc
Removing a cat or two in your system also increases the noise. But legalities again...
