nah, the cat, just filters the exhaust, reducing some of the hydrocarbons......as far as affecting the engine, it should wake
it up a little as you are unrestricting the flow of exhaust. if you
don't have emissions testing, i'd get a weber & a header.....but none
the less, if you just remove the cat & run a new pipe, make sure to
put a new 02 bung on it so you can put the o2 sensor back on, otherwise
if your still running the stock carb, it will affect the engine operation...
as far as being loud, it shouldn't affect it too much, bout the same, maybe
a decibel or two more....
