Lexus is 2016 axle back with 2017

I want to get an axle back exhaust for my lexus is 200T 2016, but all of them are hella expensive priced around 400. I saw some 2017 models only go for 250, and i wanted to know if it was possible to slap the 2017 model on my 2016. I know the dual tips will interfere, but can i just cut the bumper or tilt and angle it like an Rc?
