heres a nice list for you to consider:
1)Gears (4.10's or 3.73's) people are divided over which is better, some like the 3.73s better for dialy driving, however 4.10's will get u a better time at the track. Another thing to consider when deciding on gears is that based on what ive seen in this forum, there a MORE people wishing they got 4.10s over their 3.73s, then people wanting to downgrade to 3.73s. I suggest going FRPP over motive, FRPP is a higher quality
2)This next one can be switched with the first, depending on how much money you got/want to mod, but the second thing would be a short throw shifter. These will make you have better shifts, giving you a better time(possibly if at all) Good brands to consider are MGW, Steeda, and Pro 5.0
3)Next is exhaust, catbacks and midpipes are all subject to the buyer since everyone has different tastes. Rule of thumb is with chambered catbacks, they sound deep and throaty where glasspack/resonator sound like high performance Nascar type of sound. As far as mid pipe, X pipes sound more exotic (better gains up high), and H pipes sound deep and throaty. Another rule of thumb, never put an off road midpipe on a glasspack catback, otherwise it will sound like machine guns firing and sound really bad, unless u want obnixously loud exhaust
4)To finish up the exhaust, headers. LTs vs Shorty. Depending on your emissons, go with LT's they yield a higher level of performance, however these do tend to sit low, so if clearance is a problem, go with shortys. If emissions arent a problem, go with long tubes since shortys take the SAME amount of time, and blood to install(if your doing it yourself) LTs give you about 12rwhp where the shortys will prob on gain u about 5-8
4.5) A nice intermediate step between the 4th step and the 5th step would be to do a nice 10 min mod that will only improve your performance, costing around 400 bucks. This would be a TB/Plenum combo. A good brand to consider is Accufab. These will not gain you as much as headers and cams but only increase the amount of power your car will produce when u start adding more things to it. You can also add a CAI at the point as well if you want as they dont really do anything for our mustangs unless youre putting out some performance. You can do the CAI as your first step, but dont expect to see more than 2rwhp IF that
5) After headers, cams would be a nice next step up. Two popular brands on here are Comp Cams and VT cams. From peoples dyno sheets, you can expect to see 25-30rwhp VT Stage 2 cams. YOU NEED A TUNE WITH THIS MOD! I suggest getting this tuned at the same time you install your headers.
6) Get a custom tune! After these mods, I would suggest to not do any more performance mods to your car until you do some suspension mods, power doesnt do you any good unless you can put it to the ground
If theres anything else that i think of ill be sure to list it. This list should get you started modding. Note, this list does NOT have to be done in this order, but the order that i put these things in follow a certain logic If theres anything you have a question on, just ask. I may not be the one who can answer, but someone will be able to help. I hope my explainations help
