1. If I get a dual cat back what difference would it make besides noise? Also at American muscle they sell exhaust for my car would that just bolt on and would I need to lift the car to do this?

2. With the 4:10 gears how much HP will I gain and how noticeable of performance would it make, and will I need any more parts for it?

3. What parts do I need to hook up fog lights, and are they hard putting in ?

4. Will 01+ headlights (fogged) fit in perfect?

5. With xcal does it add a noticable amount of power?

1. you will gain performance, and i need to see what exhaust your talking about.

2. gears don't give you horsepower, they allow you to use your horsepower you have more efficiently, by making you accelerate quicker

3. go to www.vmptuning.com get the fog light wiring harness...comes with everything but the fog light assemblies

4. if your car is a 99-04 all the oem style fog lights will fit

5. yes.

Right now I'm completely stock 00 auto and my acceleration is horrible I don't know what my 0-60mph time is but I would guess it's around 8-9 seconds how much time would 4:10 gears shave off that time? Also do I need a new rear or something like that to have 4:10 ?

[Redline]

also what is better to race with over drive on or off ? I don't really know what overdrive is but with it off it feels like it has more power.

well OD is just what it say's OD its that part when your driving at a certian speed and you mash the peddle and you car hits a higher RPM thats the OD , and to race with it on would not make a difference because overdrive only kicks in at a certian speed and RPM so i would say leave it off and keep racing on the track not the street's if you wanna keep your 00 stang

[Redline]

I don't race on the street much. So I still don't quite get OD still, when I'm driving and floor it it stays same rpm then a second later it's at 4000 rpm that's over drive ?and with it off it wouldn't jump up to 4000rpm ? So is it like a completely different gear or some thing, sorry but I'm kinda car stupid at the moment.

Oh and I read that with 4:10 they only top out at 107mph is that true? I don't think it's a bad thing because that's still very fast for a street car but would like to know.

Overdrive is Stock in automatics so when your driving and you mash the peddle depending on how fast your going already OD should kick in for a few then turn off unlike Us Manual drivers we need to make our own Overdrive by DownShifting,
Now you should not have to turn your OD on in order to do this there might be a problem with your tranny if it doesnt do this without you having to turn your OD on and as far as the TOP out with 4:10 gears from what i know you top out is what your GOVERNER allows and of course before your car blows up which ever is first.

Well to be honest I just found the OD button afew days ago it was always on when I drive so when that happened OD was on, I doubt there would be a trans problem this car went through there 100 point expection.

I may be stupid but I still don't get OD with it off do I get more power?

I don't think you're right about the top speed for those gears because they are made for acceleration and if I learned any thing from grand turrismo is that better acceleration lower top speed lol. I'm having the govenor removed some time soon but I know the 3.8 can take alot of abuse from what I heard so it will not blow up (i hope).

overdrive is your top gear. in the auto- it is 4th, in the manual- it is 5th

for the auto, turn off o/d and it will run as a 3speed. this is how i race in the 1/4

+1 when u mash on the pedal on an auto it just down shifts like a manual. OD is your 4th gear. OD is not when it down shifts when i give er shit lol

1: cat back from the Y pipe just changes exhaust note. no real power gains are seen. you can bolt on an off road H pipe and a cat back for the same year GT mustang with nothing but hand tools, a jack, and 2 jack stands.

2: gears do not add horsepower. steeper gears can actually cost a few rwhp, but the acceleration gets you into the powerband much quicker, and this gets you to your peak rwhp range quicker.

3: VMPTuning has a kit. you need to cut out the bumper grill over the foglight holes and screw in the self-tapping bracket. then run the wires to a positive 12V source, run the wires to a switch, and voila!

4: yes, but check out the jdm smoked clears from ebay. they are glass, not plastic, and will not decolor that hazy yellow.

5: depending on tune, yes. this is most beneficial on an auto because you can also tune the tranny to shift at different speeds, rpms, and different firmness to the shifts.

wow so OD off is faster!! that is crazy because I beat a 2006 v6 dodge charger last night by half a car length we hit just under 100mph. I had a bad start too damn one wheel spin had to let off the gas to get control again.

its not faster just turning it off allows the car to sit in its power band in 3rd gear rather then switching to the relaxed ratio OD gear

no. not faster by any means. not unless your car is tuned for power mode with overdrive off only. it just runs without 4th gear.

Well are you guys sure because when OD is on I hear and feel it flipping gears. and why would the petal feel stiffer when OD is off ?

my pedal don't feel stiffer... the only time ive ever heard of a stiff pedal related to tranny problems is then u have bad valve body wear.

it is in your head

[Redline]

well it's only stiffer when OD is off when OD is on the petal is loose.

+1 ill have to side with you on that

u want to feel a stiff pedal hop in a 5 speed lol manual transmission cars have a stiffer spring to prevent accidental over revving from a soggy pedal
