exhaust vs tune

[15xSTIx]

Feel stupid for asking but didn't run into it with the cobalt...

For a cat back exhaust a tune is not required correct?

 

[HolyCrapItsFast]

That is correct sir :tup:

Everything engine wise that you do to your turbo Subaru, short of a K&N Drop in Filter, requires a tune afterward. Everything.

Except a cat back exhaust. :tup:
