It will be brutally, violently, unpleasantly loud - to the point that it can cause hearing damage - and will give you maybe 2-3 horsepower.

If you're lucky, the car has the stock exhaust.
It is not restrictive at all, and it's quiet. Don't mess with it.

You might actually lose horsepower, the system is designed for a certain amount of back pressure. In general, there's no benefit at all to going catless, and if you do you have to deal with the smell. Also, there's a reason that cars have catalytic converters, the level of pollution is a huge amount lower than when they didn't have them.
Welcome to the Forum, keep asking questions, there's a lot of great knowledge and information on here.

Oops! Sounds like a no go area. Thanks for the head ups.

Like others have said that will be brutal. Ive run stock diameter with just a muffler delete and it was too droney on the freeway it hurt my ears. I now run stock pipe diameter, stock cat, stock resonator, no muffler with a dump just before the axle and it's loud but no drone. If I accelerate under 2k rpm it's almost inaudible. Once you get into boost it's so good because being dumped under the car I can hear it as if I were outside. I hear all the pops n bangs on a stock tune lol. I must say though it is loud on the freeway as you go over 2k rpm if you're gonna wanna cruise at any reasonable speed 70mph+
