Hey guys. Im trying to figure out what to buy next. Here are my options.

Flowmaster American Thunder Axel-Back Exhaust $269.99
It doesn't add any HP but I think it sounds pretty sweet. I haven't heard it in real life but saw some of the videos on YouTube.
Flowmaster American Thunder Mustang Axle-Back Exhaust (05-10 GT & 07-10 GT500) at AmericanMuscle.com - Free Shipping!

BBK Twin 62mm Throttle Body $319.99
I already have a Steeda CAI + Tune. The throttle body is supposed to add 10-15 RWHP and 20-25 RWTQ (at best around $21.33/1 HP)
BBK Twin 62mm Mustang Throttle Body (05-10 GT) at AmericanMuscle.com - Free Shipping!

Steeda Underdrive Pulleys $214.99
The HP gains on this one are supposed to be up to 10HP (around $21.50/1 HP)
Steeda Mustang Underdrive Pulley System (05-10 Mustang GT) at AmericanMuscle - Free Shipping!

BBK Underdrive Pulleys $249.99
The HP gains on this one are supposed to be up to 12HP (around $20.83/1 HP)
BBK SFI Mustang Underdrive Pulley System 4.6L 3V (05-10 GT) at AmericanMuscle - Free Shipping!

What do you guys think? Im open to possibilities.

I did not like the flowmasters on my car,especially when i went with an or h pipe. I would go with the udp's and a tune. Forget the tb sspacer.

The Underdrive Pulleys don't need a tune right?? Also any preference on the brand? Steeda vs BBK? (on AM.com the BBK costs more and gains 12HP but has only 9 reviews whereas the Steeda costs less, has 10HP gain and 31 reviews.)

dunno why u tuned already....ur supposed to do that after mods...but im sure it helped....

either pullies will be fine, every car is different, pulles that advertise 10hp may give you 8 or 12...you never know.

im assuming this is a daily driver.......maybe some gears

^ I bought the car 1.5 yrs ago and it already had the CAI on it and I'm assuming it had a tune as well. I'm not 100% sure but CAIs require a tune.

Yea you should also consider getting say 4.10 gears if its an auto, or 3.73's if its manual. Im gunna guess it is manual?

Its actually an auto so the 4.10 gears would be nice. Iv been considering getting those for a long time but with the installation, they would probably cost me around $600 or so. the underdrive pulleys on the other hand are $200 and install is no problem.

Yea I hear you man, go with the undedrive pulleys then, just remember it does take a little power away form your accessories like your air conditioning.

Drom the list I would go with the UD Pullies next and continue looking for mufflers. Unless you are adding long tubes to your car you aren't really going to be picking up that much if any HP by swapping out mufflers. I have heard the Flowmasters on Greggs car when he had them and a couple in person and while they do sound decent I have heard some better ones out there

Glad u decided to pick up the udp. Thats wat i was gonna recommend to u. Forget throttle body unless u supercharge n imo flowmasters r for trucks. They dont sound as good as others on stangs, ive heard a few different kinds n flowmaster has always been my least favorite.

Flowmaster are junk, and belong on trucks, and old big engines. There are so many better exhaust out there. Check out Spin Tech's. SLP makes a nice system also. There're a bunch of systems out there.

I have just installed the flowmasters thunder series and i have to say i love the sound.

I am a working student with rent and bills, so i could not afford the corsas or the stingers which would have been my first pick. I have to say for the price i am extremely happy with the new sound which i would say is almost twice as loud as stock but when idleing is not that bad.

For the money, i would agree with the rest that the throttle body space doesnt do much either.

UPDATE: I installed the UDPs this weekend. I have to say that the throttle response is much better and I feel a little bit more power at lower RPMs. Haven't seen any MPG improvements yet. The install was a B**** because I didn't have an impact wrench and the pulley puller was too short but eventually I found ways around it. Having a second person definitely helps :). Overall its a pretty nice mod and I only paid $128 so I got a pretty good deal. :awesomework:
