With the auto I don't think it will be to bad. How do your 4.30 gears feel? is it to much shifting? is 1st gear useless?
Still tuning but it doesn't bother me at all. Well, the Motive gear whine is annoying but I've managed to get it tolerable.

I recommend letting the installing provide every last part and fluid and go with whatever gear brand they want. When I did mine, it was my understanding Motive might make some noise(not a great deal) which I'd have a good tolerance for....but this was PIERCING whine on the hwy from 50-65 and quieter on either side of that tapering off to no noise. Quiet from 0-40 and again from 70 on up. If you drag race, shoot for 4.10's in the brand they want and just run 26" tires out back for a little more rpm.

The ceramic stainless shorties for the 5.0 are $570. I'd pay that for better quality over the. BBKs or Mac

JBA is also the only company to have CARB legal / 50 State headers as the others did not get theirs tested.

I checked into this as I needed to be legal on my NEW 2013 5.0L in California. I attached the letter JBA sent me when I ordered my JBA shorties for my new 13.
