Another Happy Kooks customer Just wanted to let everyone know how pleased i am with kooks headers there ORY. The sound is much better then the factory system and it feels much more powerful throughout the powerband. I also want to thank HPE for installing it they did a great job and they also allowed me to strap in on there dyno 
. I didnt have any numbers before the headers but afterwards i made 324.95 rwhp and 331.6 lbft. of torque which i am pretty happy with for stock tune and using the 50% baffle on my borla catback. Another thing i found interesting was a brand new 2005 mustang GT only made 261 rwhp no wonder they dont put up much of a challenge for a stock ls1.
