Notice any improvement on gas after installing the exhaust and throttle body?

Also how did you recalabrate your speedo after changing the gears?

[burtonsnow157]

came with the 3.73's but the shop can do it

[Meanstang96]

What kinda rpm's do you run on the highway at say 70mph cause i cant decide between 3.55's or 3.73's? Love the car though sounds like a stang should!:)

[burtonsnow157]

thanks man. get 3.73s for sure. at 70mph im at like 2100rpms

Is this deeper sounding than a Flowmaster 40 and H-pipe combo?

@burtonsnow157 I've got an '02 GT and they really do get kick ass gas mileage on long trips! My current V8 gets about the same gas mileage on the highway that my last 2.3L I-4 in my old Mazda6 got. That's sad for the Mazda, awesome for the Mustang, even though they're both technically Fords.

Your Mustang sounds great btw!
