Pypes v6 duel conversion kit for exhaust.
JLT CAI, with SCT SF3 tuner.

this will set off a landslide of information.

I feel that in the begining a low cost and almost immediate improvement would be a CAI and 91 octane tune accompanied by a single low flow (GT takeoff) muffler will give you the most bang for your buck.

(dual exhausts look good but do little to improve performance)

After these everything else is gravy...lol

Hey welcome to the forum!

You are on the right path. The Cold air intake (Just called CAI around here) and the tuner combo is the first step for anyone. It's a night and day difference.

Also the dual exhaust is a must for not only looks and performance but also sound. I don't know why but it sounds SOOOOO much better when you have a dual as compared to a single.

If I were you I would get my tuner from AmericanMuscle.com because they offer free tunes for life. That means if you get some new headers down the road you call them up and the write you a tune to optimize the performance gains that the headers will offer (However, headers do not offer much).

Also before you get a exhaust kit check out a mustang with a H pipe on youtube first. An H pipe sounds a lot throatier but offers less performance. Its up to you. My exhaust shop made me a custom H pipe and installed 2 flowmaster mufflers for 250$ installed. If you want a vid of my exhaust let me know.

For your next mod, after the exhaust and tuner, I'd look into a 8.8 rear end and gear combo from NewTakeOff.com. That is what most of us are doing to make our V6's fast. Oh and be sure to check on craiges list for cheep GT tires and wheels. They have some nice wide tires that you will like.

Check out www.newtakeoff.com for the dual exhaust kit, its made by pypes and has everything you will need for the install, and has GT mufflers. For the JLT CAI and SCT Tune get the combo from www.americanmuscle.com

all of this will put a smile on your face.

Depends on what you wanna improve? Sound? Acceleration? Handling? Braking? N/A or F/I?

Assuming N/A, don't do duals if your initial goal is improved acceleration cause they won't get you there. Duals will really shine on an FI app and I've heard those running boost report 10-15hp but that is under boost not N/A. You'll likely see 0-5hp max on a stock app.

1- CAI and Tune
2- Gears Tlock

1 & 2 will give you >90% of the performance gains available to an N/A 4.0 from a throttle response and seat of the pants, tire barking kind of way.

In terms of off the line acceleration. Gears does it. Duals doesn't but makes you sound better.

Get some gears and you will know my young padawan.

yeah duals are a let down if you dont have FI. Been there. A good single meffler will increase your performance. Dont bother with headers either ,until youre ready to go all out FI. Again been there,,,
Got it all now and it seems to be a well rounded finished product...

They used to have the 8.8 with 3.73's but that is definitely what I was referring to.

Also the Dual exhaust may not add much performance wise, but it really does make the car sound and look better.

This all looks and sound amazing! In all honesty, how easy is the instalation of the CAI? I mean... I change my own oil but thats about it as far as my tech skill/experience. It looks to good and easy to be true. I just dont want t o mess anything up. Also, this mustang is my daily driver. Does this hurt the engine or reliability at all? I think this would be a great start to my 09 4.0 V6. I dont know about the exaust yet but maybe someday. I am very excited about the CAI and tuner combo on americanmuscle.com.
