This pipe should remain stock or 3" and not exceed 3". If you decrease the size anymore than stock you may get to much back pressure.
In all my research the best exhaust system is the 3" si/3"so system or the 3" si/do 2.25 or 2.5.
Now if you want check out Banks they have a good one with a lot of r+d into it.
