I was wondering if anyone could help me. I have an 08 6.4 F-450 i am lookin 4 a dpf that has no internals but looks stock. I am on my 3rd one and just found out that the exaust system on my truck only has a 50,000 mile warrenty. I have 47,000 on it now.The next time it clogs up i'll have 2 fork out $ 2,800 dollars. Ford has replaced the motor all the coolers and the complete exaust system 8 months ago. By the the way if u were wondering what that costs it was $ 31,000 and some change thru ford customer pay is $ 39,000. So if anyone knows if something like that is around please drop me a line will b verry greatfull
