Gas Milage decrease... not much, depends on if you drive a lot of town or highway.
Accel increase... possibley one of the best bang for buck parts you can buy.

My opinion... YOU'LL LOVE 'EM!!!

what im woundering is how much of a difference there is, like how much time is taken off your 0-60

i went from 3.27 to 4.10s and on the highway i got about 20-23MPG, in town i got 8-12. Now after the headers and midpipe i got about 25 on the highway

I have 4.10s--I drive 11 miles to work everyday, almost all freeway with a little around-town driving and average 16-17mpg on every tank. I put my foot in it most of the time, but not to-the-floor, balls-out revving the sh*t out of it. A recent trip from L.A. to Vegas gave me 22.5mpg, averaging 80mph which puts rpm's @ about 3 grand. I don't know about 0-60 times, but you can feel a huge increase in torque and the acceleration is very noticeably better. SUMMARY: well worth it for me!!!

+1...

I just swapped from 3:27's to 4:10's in my 01 Cobra and all I have to say is WOW. Enough said. The performance increase is sooo nice that gas milage doesn't matter anymore. Plus gas milage shouldn't be important in a sports car. They suck gas as it is...

i did it with my vic and i went from 20 mpg to 17 when i switch but if i put it to the floor it just rolls smoke off the tires idk i don't mind losing the 3-4 mpg for the increase in power i mean its worth it to me i love being thrown back in to my seat when i put it to the floor .i mean also the vics heavier than a mustang and the 4.10s really gave the car a wake up call.
