Borla cat back system question

[ZR2]

Hey awesome people,

I’m about to pull the plug on the whole Borla catback system S-type and i got a question on the pipe diameter as i see they come in 2.5 inch or 3 inches and the 2.5 is more expensive than the 3. If someone can provide an explanation on the attached options, that would be appreciated.

140916 is true duals and you have to cut into factory piping. 140914 is a cat back with no cutting required.140915 is similar to 140914 but with a louder muffler. I had the 140914 on my 2022 and I liked the sound except the shotgun start when cold. Hope this helps.
