i recently went down to mustangs unlimited in conn. the other day and the dude at the desk says that the exhaust for my 02 gt is the worst thing on the car and should be replaced with aftermarket exhaust first more than any other mod..is this true..?

 

im not so sure about that. gears arent bad on em but id switch them first. 3.73's.

 

i do some highway driveing but allot of around town type stuff....how bad will be my gas milage if i get 3.73? i dont fully understand what they do just yet.. do they make your gears ride out longer? i hope so cause first gear is soooo short. thanks

 

They make your gears wind up quicker, which'll let your motor get into it's powerband quicker in every other gear. Granted, it'll feel like you gained power, when you really didn't.

As far as the exhaust, flowmaster did some pretty bad ripping on it on their site. It's not loading correctly right now, but I think they said it was 2" crush bent. Puky on a motor that big<img border="0" src=smileys/smiley5.gif border="0">

 

thats why you have your exhaust shop bend you 2 1/2 or 3 inch pipes. your gears wont hurt you too much, i get @ 250-300 a tank, depending on my combo of city and hwy miles. with 3:73's, i coast on the hwy between 2200 and 2500 rpms, betweeon 60-75 mph.

 

well with stock i know that 70MPH is around 1,900-2,000 rpm on 5th on mine

 

sound like a saleman there...if your worried about gas 3:55 will be ok and while in town just short shift will save you gas i go 1-2-4

 

get the exhaust and the gears they will both make a difference.

thats probably the first couple of mods that should be done on any stang</P>

 

Stay away from the 3 inch exhaust, it will actually hurt performance from what I hear on stock motors. If you have forced induction, then 3 inch is good. Exhaust was the first thing I changed out on my stang. I was definetly happy as I increased gas milage, well when I wasn't getting on it to hear the deaper, more throaty sound of the exhuast<img border="0" src=smileys/smiley4.gif border="0"> !
