Can anyone tell me how much my RPM might climb up to at cruising speed on the freeway, 75ish, if I should go 4.10's. Im considering 3.73's just so i dont have to hear my loud ass exhaust on a long drive. I think im right around 2200 rpm now and i believe 3k or 3.5k is when my exhaust gets really pissed off. Thanks for any input

its not nearly as horrid as you think... if you do a TON of interstate you may want to consider 3.73... i have no issues going 75mph.

You might loose some mpg but the motor will rev a little higher on the freeway. Should have no problems.
