not sure as to which barrel you are talking about.... thing is , that if you are just going to change the barrel and leave the cat, the it would be less noisy as opposed to removing the cat as well as the stock barrel...
if you just like how the barrel looks, then a simple change will keep it sorta quiet.... thin is, most barrels will have a 2 inch or 2.5 inch inlet, and the stock piping is about 1.5 inches....may have to change the pipes from the after the cat to 2 inch, but remember that with the cat, the airflow will still be restricted.
