Will edelbrock headers on a 04 GT Mustang add horsepower, and how much?

You may see about 5 HP at the rear wheels. Headers will scavenge the exhaust better, and I would install an X pipe at the same time. Better breathing equals better performance.



Today's engines and computers are generally tweeked with lots of small gains. Unlike the cars of the 40's through the 70's.

A big gain can be seen with a reprogrammer such as a Bullydog (one example)Will edelbrock headers on a 04 GT Mustang add horsepower, and how much?
It may help some. Most engines nowadays are computer controlled, and the addition of headers will help get heat and exhaust away quicker so engine may breathe a little better. Catalytic converter and computer controls will compensate out a lot of the gains made by the headers. You need to consider a chip upgrade and a cold air intake kit to get real results.Will edelbrock headers on a 04 GT Mustang add horsepower, and how much?
Yes they will add power. My guess, 8-15 HP at the crank.
