Scorpion back box

I've got the scorpion system with the middle box chop and it sounds sweet, has some nice pops and bangs! Looks great too!

 

Ive got a scorpion cat back and like it, its not to loud but has a nice boom on boost and as Minchy said, it pops n bang well also fills the holes up nice in the bumper.

 

If it's just the back box I wouldn't expect any major change in noise to be honest.

 

Try this link it's a vid of my scorpion with no centre box!!
