I got true duals put on my 2002 F-150 with a 5.4 about a month ago, I noticed after driving a awhile the right pipe has a odd putting sound. It has a fairly consistant beat, and at cold startup or after an hour on the highway it isn't there, mainly after driving around town for awhile. The guys at the exhaust shop think it might be the rear cat, which I find unlikely with only 49k on a truck that runs perfect with no check engine light. If it is the cat I told them Ford would get to look at it first for warrenty which they didn't like, they started spouting off about how the exhaust is now altered and the warrenty is now void (it shouldn't be). If I had to do over I would probably go to a different shop, and I will when it is time to dual my Ranger.
I had them put on 2.25" duals after the stock cats with Thrush glasspacks, it sounds great from in the cab as you can't hear the strange noise from there. Any ideas what would do this?
