what is the biggest difference in 2.5 and 3 inch exhaust? i wanna order one but dont know which one is better for our cars .. is 3 inch much louder?

Stick with the 2.5. A couple of my buddies are in the 600+ range with 2.5 inch exhaust.

3" is overkill for an NA application, even for mild SC or turbo set-ups.

Stick with a 2.5" as recommended above.
