Dual Exhaust need a new tune?
I'm thinking of getting dual exhaust on my 2008 v6 mustang. I already have a jlt cold air intake with an sct tuner. My car is already tuned for the intake do i need to update my tune for dual exhaust?

Chances are you don't need one, but you might ask your tuner; those are the guys who know.I'm thinking of getting dual exhaust on my 2008 v6 mustang. I already have a jlt cold air intake with an sct tuner. My car is already tuned for the intake do i need to update my tune for dual exhaust?
As long as you only made changes from the Cats Back then your fine, (no need) to up-date the Tune. If you added Headers you would need to:bigthumbsup
