  • knocking sound

    After I put my headers on, there has been a knocking sound at my feet when I reach higher rpms and when I'm turning sharp right?? Any suggestions on what this might be?

    I think I saw where there is supposed to be some custom bending of the y-pipe for the 98+ models, and I'm not sure if this was done when they welded my exhaust back. If they did not, could it be the y-pipe vibrating off something?

    Any help would be appreciated.
