I was just going to get headers but now everyone says just get gears but i didnt want them but now i decided to put them into considiration I have a 03 gt O/R h pipe shaker hood and dual flos
I dont drive on the expressway much but i do want alot of acceleration but it is my dd so i dont want to have to be shifting every 5 secs with the 4.10s
so what should i get the gears or headers i want more acceleration and if gears what kind

gears, 3:73's or 3:90's. if its a dd i'd go 3:73's if your worried about gas. You will have to get a shorty xpipe with headers, shorty's don't do hardly anything, basically a waste

a 4.10 isn't going to make you shift every second, but if you wnat a good all around gear I would say get a 3.73, but get a FRPP gear. Some aftermarket gears make noises. I have a 4.10 in my Mach and I love it. I even thought of trying a 4.30.

I would go 4.10s

There will be a noticable difference in accel with the 4.10s compared to the 3.90s, and the rpms at 80 mph will only be 130 rpm lower with 3.90s compared to 4.10s

Top speed shouldn't matter...because of aerodynamics we can only go about 144. If top speed is important, keep your stock gears

If you run all the way to 6K rpm in 4th and you have stock height tires (245/45/17 or 275/40/17 or 315/35/17), you will top out at 112 mph. If you go into fifth and you have enough power you can get to 180 mph (assuming you have a T-3650).

I don't drive my car very much at all, but around 2600-2700 I would say is accurate. I love the 4.10, and You will too. I highly reccomend it.

That I don't know, but the 4.10 is going to give you more pull down low. You'll have plenty of top end left with the 4.10.

yeah just make sure to get the bearing kit. that way you won't have to replace them quite as soon down the road.
