definitley dont keep the stock headers unless you have to, go ahead and get the shortys, you will be glad

 

stock headers have been proven to not hinder power up to 300hp, so unless u have huge power plans in mind, shorties are useless and even after 300hp shorties wont really help u, lt's on the other hand will help u out in power on a stock set-up and with a power adder

 

if u get a catted H-pipe and pass emissions, let me know if u can make me one and i'll buy one off u. i got LT Heads wit no cats... i didnt know they were gonna come off til AFTER they put it on..[:@]i still havent gotten pulled over yet.. been driving in cali too long without cats.. and cant find a spot to do some for me.. i think i havent gotten pulled over because i dont drive a rice rocketand dont drive like an idiot.. other than that, you'll enjoy your sounds once u get the LTs... they made my car sound deep;the exhaust alone sounds nice, but if i did have that kind of money, i would've went with a Borla... but im still happy.. and you'll be happy too.. enjoy driving ur stang.. like the rest of us..

 

Umm, no.
