Turbo back by magna flow 3.5 " to 4" magna flow even says it will not void the warranty what should i do.
Have a civil talk with the dealer and find out what the reasons are for not covering the turbo. If this is a common or at least a known replacement issue on the '03 trucks, then you should be o.k. Find some info/tech. write ups on the turbo issue and bring it to the dealer as...dare I say...."ammunition", if they try to say your exhaust "caused" the problem. You might want to call Magnaflow and ask for a copy of the warranty protection guarantee and bring that with you to the dealer. Bring a copy of the Federal Magnuson-Moss Act and highlight portions that pertain to your issue. (You might ask a lawyer for advice/assistance, most will for a nominal pre-determined fee.)
This is an example of the portion of the law that protects you:
Tie-In Sales" Provisions
Generally, tie-in sales provisions are not allowed. Such a provision would require a purchaser of the warranted product to buy an item or service from a particular company to use with the warranted product in order to be eligible to receive a remedy under the warranty. The following is an example of prohibited tie-in sales provisions:
"In order to keep your new Plenum Brand Vacuum Cleaner warranty in effect, you must use genuine Plenum Brand Filter Bags. Failure to have scheduled maintenance performed, at your expense, by Great American Maintenance Company, Inc., voids this warranty."
More clearly and pertaining to your issue...
"In order to keep your new Ford truck warranty in effect, you must use Motorcraft filters, oil, parts and, in your case, an OEM Ford replacement exhaust. Failure to have scheduled maintenance performed, at your expense, by the Ford Motor Company, voids your warranty."
So....the only sticky part is the "kitty". See, the feds don't like you not having one on your rig. (Sort of illegal.) Ford also says "off-road" equipment voids the warranty. I don't think you can do much w/out the cat on your truck, being it would be for "off-road use only". Frankly, I don't see why you need a cat on a diesel anyway. It does nothing. Ford didn't even put them on some years. You could use that approach also. I don't see how lowering the EGT's at the turbo and reducing neg. pressure on the turbo could have ill effects. They know it helps the turbo last longer. Sound like they just don't want to pay. I think you have some ammo and a strong case for getting the work done. Do others agree?
