i have ordered the ninja cat back from scoobyworld and just wondered what the difference between that and the normal ninja is, anyone able to give me abit of an explanation as i'm not brilliant with that sort of stuff

 

a few more horses and an even better soundtrack

 

on the cat back?

 

If you have a 1993-2000 Impreza with the cat back system you will get the back box and a centre section. The Ninja centre section will replace your standard centre section with a stainless steel pipe with fast flow silencer but no catalytic converter. The standard pipe it replaces has a cat in it therefore you should notice a good increase in performance. On a 2001 Impreza onwards the same applies but you are not removing a cat as there is no cat in the standard pipe that meets the back box.
