i concur!

It will not hurt anything as long as cold air does not rush up when you shut it off....just close to the exhaust before shutting it off. You will see super comp dragsters have flappers tp stop this.
It will be louder and sound good but on some engines (L98,LT1,LS1,2and7) you need back pressure to produce ultimate horsepower
