Just because it is your daily driver doesn't mean you can't get 4:10's. for the cost to have it done, anything less wouldn't be worth it. I have been driving mine daily for the last 10000 miles with my gears, and they are great. but definately exhaust of some kind. I'm still waiting to order a shifter. lowering springs are nice, if not done already. good luck, check back with some specific stuff.
