how much will new headers help?

I got a airaid intake put into my 2012 aswell as a magnaflow catback exhaust.
I'm stuck between getting new headers or black front lights or even 185$ for a new hood scoop.

Will headers make me faster? Louder?

 

More noise that's for sure.
Idk about gains but mpg will take a hit ,since you will be stepping on it almost always.
Installing some 3rz lce headers soon on my truck ,will report back.

 

MPG will take a hit as in better mileage or worse?

 

I dont know anything about headers but what said scoop are you talkin about for $185??

 

you can also do the blhm your self as its pretty easy

 

well headers will for sure make you louder so you may seem a bit faster haha. and he ment mpg will take a hit as in nose dive into the ground...when you have something where you like the sound of it your going to step on it to hear it more which means mpg will be dropping pretty fast.

 

The dealership where I got my truck said for 185$ plus tax I could get a new hood with a scoop
