My dynamic t-jet 120's exhaust sits behind the rear bumper and doesn't poke through like the sports do. This doesn't bother me as I don't mind not seeing the exhaust. What does bother me is the back box connected to the tip is quite low. So much so that when reversing to a gutter if I have someone sitting in the back it knocks. It is all cited correctly. It's not lower than how it would of come out of the factory. It's also very visible when driving behind the car and is a bit ugly. If I was to replace the back box is it possible to get smaller ones that sit a little higher up. I don't want a whole new exhaust. And I don't want any power gains or fancy noises. I jus want to hide the box and stop it catching gutters?
