ChinoHillian Posted June 5, 2011 Report Share Posted June 5, 2011 (edited) I just did my longtube install and now I have a rubbing or vibrating noise coming from my exhaust somewhere. When the truck is in park on neutral there is no noise but drive, reverse or 3 2 1 makes the vibrating sound. It is coming from under the cab so could it be from a loose bolt or my y pipe not having the pipes flush against the y pipe? Edit: it does do it in neutral but not as bad. Only happens when I'm stopped or creepin under 10 mph Edited June 5, 2011 by ChinoHillian (see edit history) Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted June 5, 2011 Report Share Posted June 5, 2011 Is your header kit OBX or Dynatech? Quote Link to comment Share on other sites More sharing options...

Fireman31 Posted June 6, 2011 Report Share Posted June 6, 2011 (edited) The vibration you hear/feel is because 1 of the 2 slip joints in the midpipe kit has come loose. The band clamps that come with the kit really suck, I had the same problem. Even if you slip the pipes back together and tighten the hell out of the clamp, they will loosen again in time. I wound up having the slip joints welded to avoid any further issues..... Edited June 6, 2011 by Fireman31 (see edit history) Quote Link to comment Share on other sites More sharing options...
