I already Have a Steeda Cold Air Intake, Power Pulley, Helix Throttle Body Spacer, Bassani X-Pipe, and Magnaflow dual exhausts.
What else can I do to my mustang to make it faster and better?

 

get a tuner

 

Do gears and a tuner!

 

blower?

 

shift kit or a short throw shifter and get rid of the throttle body spacer, not sure if anyone has made one for the 4.0 yet but a intake manifold spacer is a good mod

 

forget the
Helix Throttle Body Spacer
Steeda Cold Air Intake
Bassani X-Pipe


the cai is like 2 hp and u can get the same thing with a new filter and removing silencer
spacer does nothing at all
and the bassani doesnt make a x for a 6 as far as i know and a gt x will not work on a 6 just get divoreced mid or a pypes x if u want the x

and save for a tuner gears and a lsd and either a short throw or a shift kit which ever u are manual or auto

 

look at his avatar. he has a S917.

 

no he has a s197 and they may make a x for them

 

Gears/Tuner/Stickerzzzz

I cant remember who it was, granatelli or someone but they made their own MAF tube that got rid of the restriction from it, other tubes that have the stock maf tube size dont gain any extra power, its mainly from the tuner they use. Im not sure about Steeda intakes like you have.

Cams are always great ways to build power.

Your best combination would be
*Blower
*Cams
*Gears
*Tuner

You will be perfectly happy with that.

I suggest an STS turbo system, it is one of the most efficent systems out there meaning more power for less pressure. Its safer for the car.

Also if you dont want to go that way I hear great things about Stainless works 3" exhaust system. Just in case your not happy with yours.

I really dont know too much else about the S197 other than I would love to have one.
