Hello I'm zach. I have a 2007 f150 with a 4.6l triton 2wd. All stock but beyond repair. It's running but almost nothing works anymore on it. It's been in 4 accidents and ran over (yes over) 4 deer, last year I had an accident where I was pulled off the road at 40mph by the backdraft of an 18 wheeler passing me at 60 and it shredded the exhaust. Now I don't even have heat because the exhaust fumes come in through the air ducts when on. I have a guy who has an exhaust system from a 2002 (same wheelbase) f150 with a 5.0. What I want to do is put the cats and y pipe on my truck reusing the manifolds and then running new pipe my self to make a side exit system without a muffler. My question obviously is will it bolt up? I know a 5.4 exhaust will bolt up with some difficulty. I don't mind if I have to bend or cut and clamp but welding isn't much of an option for me. This truck isn't worth putting money into. I just take it to the dump and to job sites to load with trash. This truck is surprisingly tough so I don't want to just junk it but I can't drive it as it is. Uncatted exhaust is deadly. Thank you for your time.
