2.5" or 3"

Should i go with a 3" cat back system if I plan to get CAI?

If you're planning on spraying, get the 3". Otherwise, go with the 2.5 or 2.75".

&lt;--Has 3 and did notice low end loss of power. Yet high end it gains back. It's all up to you. 3 is a really deepish flowing sound with the flow 80.
