I've got some old high-flow cats still in the boxes from a Vette I used to have.
Since I'm considering some exhaust changes to battle drone issues, I'm thinking of having the shop put these high flow cats in at the same time.

Will doing this require a tune afterwards or will the computer adjust on its own?
I'm not ready to have problems with the warranty.

Thanks in advance
