jerryj I used the Banks Cold air intake and their header w a fat turbo muffler to clear the lift kit 4.0 sounds sweet and made a good improvement.Let it breath on both ends makes a big difference.Theres a lot of restriction on a stock header.

you can increase your gas mileage and horse power by installing headers and flow through mufflers. It will change the sound of your exhaust, but that depends on which mufflers you decide on...you can get anything from quiet mufflers to extremely loud ones, but I would check my local noise ordinance laws before I invested in the latter.
