My m8 did it to his Scorpion on saph,was very loud

Scorpion system have got a small backbox,and a bigger middlebox,so they are loud if middle box removed.
My Mongoose has had the middle box removed,but the mongoose has a big back box and a small middle box,so not as loud as a scorpion

IMO Scorpion is too loud with middle box removed,all depends how loud you like your car though
