Right now I have lt headers with 3" pipe n 3" y pipe but I was thinking of eliminating the y n go straight to 2 mufflers so each header will be straight to 1 muffler any feed back if this will work

 

It'll work, but the best thing to do is to tie both banks together. Most people will do an x-pipe after the headers and before the mufflers. You can also do an h-pipe as well, just not as common and doesn't work quite as good as the x-pipe.
