JBA Headers and Y Pipe

So the name says it all. Thats what i am planning to get. After doing some research i have noticed that on many sites people have said that one a V-6 the y pipe will take power away???? is this true

 

Tell you the truth, unless you are timing your truck on the 1/4 mile, you won't notice to much lost in low end power. I'm running on 285/75/16 ATZ's and my truck hauls ass, especially above 3000 RPM w/JBA Headers, Y-pipe, Borla Cat back. Im sure if I re-gear to a 4.56 gear ratio, my truck would smoke a stock 4x4 Access Cab. Plus it sounds soo sweet!!!. this is just my opinion...
