The 2005 to 2009 Mustang GTs are still some of the best-looking Ponies to have rolled off Ford's assembly lines, and the huge aftermarket available for their 3V 4.6L V8s can transform even the most boring of stock Mustang GTs into brutal, custom monstrosities in practically no time at all. While a huge selection of 2005 to 2009 Mustang GT aftermarket parts and upgrades is a good thing, it can be a little difficult to find a good place to start. Stage 3 is here to help guide you through any number of upgrade paths to find the perfect combination of powerful Mustang performance parts and accessories for your specific goals or application.
Where should I start?
Anywhere you want. Obviously. Handling junkies head down to suspension upgrades. Horsepower addicts head to our cold air intakes or cold air intakes and tuners section. Those of who want to lay it all out on the line should mosey on over to our supercharger kit section to get a ton of power.
What are your most popular parts
By far and away, our most popular performance parts for the 2005 to 2009 Mustang GTs are our nice selection of cold air intake and tuner kits. These kits combine a powerful Mustang cold air intake (CAI) with a custom PCM tune to get you even more horsepower than a CAI or tune alone. Throwing in a throttle body, throttle body spacer, and a set of underdrive pulleys can give you an awesome power boost in a completely naturally-aspirated setup.
How do I get a better exhaust note?
All you need for a mean growl on these cars is one of our Mustang axle-back exhaust kits. Axle-back exhaust kits are easy to install, don't require any tuning or other upgrades, and are direct replacements for your stock mufflers and exhaust tips.
Not loud enough. Give me more!
If you really need to turn the volume up to the max, then your best bet will be a long tube header and mid-pipe kit, a cat-back exhaust, and a set of camshafts. Next to running open headers, this is the loudest setup you can can get your hands on. The good news is that it can get you some extra power on top of being loud The bad news is that this set up is LOUD and definitely not street legal.
What body pieces should I get?
It depends on the look you're going for. We do have several Mustang complete body kits on hand that look awesome and completely change the look of your Pony. However, most of our customers mix and match various body pieces to get a whole new and very unique look.
What supercharger kit do you recommend?
That all really depends on what you're willing to do. If you're not willing to invest in some forged internals, then the Edelbrock E-Force, Vortech's V-3, and ProCharger's P1SC series are probably for you. If you're going to make the jump to forged pistons and rods, then Whipple or the Roush Phase II TVS kits are right up your alley.
What's the maximum horsepower that my engine can take?
The absolute maximum for a stock 3V 4.6L V8 is 550 horsepower, and that's with flawless tuning, perfect maintenance, and the stars aligned just right. We generally recommend jumping to forged internals when you hit the 525 horsepower mark.
