Yes it might be larger then a full 3", but since it is smaller before the dual section
there is no real gain by having those dual 1.75" pipes. To get a gain from them you would have to make sure that the pipe before the dual section was of equal size.

a 3" tube is almost 50% bigger than dual 1.75" tubes....
Area = pi * radius^2
1.75" -> 2 x 0.875^2 x pi => 4.81 square inches
3" -> 1 x 1.5^2 x pi => 7.07 square inches
In fact, a single 2.5" pipe is about the same as dual 1.75" pipes.

i'm thinking about removing it on the stock system? because its something cheap to do?
