I am considering installing a 2.5" cat back straight pipe on my vehicle listed above sport and I am wondering will I need a tune for my new exhaust system?

Good morning,

There is no tuning the engine with larger exhaust unless you have a tuner hooked to your existing ECM.

The engine will breathe better with the bigger exhaust and will adapt to that.

Do you have a tuner on your ECM?

Okay, then there is no tuning that can be done at all.
