it would needed mapped if you removed the down pipe. but not if you only are going to get a cat back. with a 3" turbo back i have been told that you can loose too much back pressure therefore low down torque is lost compared to a 2.5" system. if you are after 340/350bhp+ get a 3" if not 2.5"

its just that i removed a system off my car and put it in my shed and put on my smaller system coz i liked the look of the angled rear silencer.
so not sure if i should put the 3" system back on or sell it and make some money for my rebuild?

The drawbacks of a 3" system over 2.5" are basically noise and possibly weight depending on how it's constructed.
