Hi,

I'm new to Mustangs, but I just picked up a 2004 V6. Like most people, I want more power. Here is what I'm considering so far:

cold air intake
larger throttle body
headers with dual exhaust
8.8 rear end from 2005+

What else can I do without having to add a supercharger or turbo?
Would underdrive pulleys be worth it?
What's better - short or long headers? (I heard long header are bad for torque)

Dave

The CAI, TB, headers, and exhaust are all gonna be mostly "feel-good" mods, you might see 20 or so horsepower from all of it combined, but it'll sound better.

As for the rear end, get one from a '99-2004 car and it'll bolt in, getting one from a 2005+ car will mean fabrication and modifications to make it fit.

Underdrive pullies are the worst mod you can do to virtually any car.

Thanks for the feedback Matt. Any other performance mods I can do?

There are a lot of mods you can make to give the 3.8L more punch. This video covers the bolt-on mods I made to my 2004 V6 autocross car. This car won a local autocross championship in 2019. The 1.8 roller rockers and the underdrive pulley are expensive, but well worth the money.

If you have any questions, please ask.

Thank you Warhorse Racing and Liccbra. Really appreciate the advice and these are mods that i can do with my son. Since he's still young, not too interested in jumping up the horsepower but love the idea of a better throttle response. At least he can be show with some go.
