You think you like your exhaust now, give it about 3000 miles until you break those things in...it sounds really good. About the gears, I bought 3.73's because I heard they were the best for a daily driver 5-speed. I also heard that 4.10's were best for automatics, but would not recommend for a 5-speed. Like I said, depends on how much you drive it and how much you're willing to spend on gas.
