well im taking the sixer in on friday to put on dual exhaust... but i cant decide whether to get 3.55, 3.7 or 4.1 gears...what are the benefits? i know that the 4.1 gets the worst gas mileage of the three..but does it have more horse? what are the benefits of each?
your horsepower will not change, it will make your accel much faster with taller gears (higher the #/ratio) but your rpms will be higher so your top speed wont be as high. Im not sure what most v6 guys do but I know for a V8 3.73 is the lowest I would go...I think 3.90 is probaly perfect. Do you have auto or std?
