I have read a couple places that there is no pre-cat in the STi up-pipe but I just read in the Subaru 2004 STi service manual that there is indeed a pre-cat in the up-pipe. is there anyone here who has actually taken off and looked down the up-pipe that can confirm if there is/is not a precat? :-?

so you have taken it out and looked or are you just repeating what you heard, I cant imagine why the Subaru service manual says in two seperate sections that there is a pre-cat, I wanna see someone post a pic :wink:
