Hey guys,

Apologies if this was mentioned. If i want to install the Borla cat back from GM. Would that require tuning? I believe it does, just want to double check.
 
No it does not require tuning. I had the dealer install it for me and no tuning done.

You never need tuning to put on a cat-back exhaust or a muffler replace.
