So I Currently have a 2.5” exhaust with headers and marriage savers on my ve ss auto. Is it worth upgrading to a 3” exhaust at all or I wouldn’t pick up any extra performance / Kw out of it?

Extractors/cats with otr & tune is biggest bang for bucks.

Catback exhaust is just for sound if that is only mod done & 3" is only small gain up top of power range.

If you change to 3" alone doubt you will feel any gain. Re-Tune after may give a small gain.
it will be the sound difference you have to ask yourself what you would prefer. 3" may drone more then 2.5"

Still got better things to spend money before thinking of 3" catback like dod delete/cam,higgins heads & stall convertor/retune

Well I bit the bullet and brought a Xforce 3 inch exhaust.
Will install it this week and then sell my 2.5 setup
