I have done it , on other cars
its fine as long as you dont mind the noise in the summer with the window down,
there are no legal or mot issues
the only other thing is it will be louder because the system will be shorter and you wont be able to fit the main box in ie the back box ,
it purely up to you i think its different and i like it ,
and at the end of the day if you want to do it go for it
read the topic please.
also you dont give the car the beans with a noisy exhaust trust me the manifold and exhaust will help with scavenging at low revs but at higher revs it make no difference at all final bhp and torque will be the same .
