Engine Builders talk.
Did you ask them over the phone? Or actually go in and ask? I've got a guy that will do it but if you ask him over the phone he will tell you to get lost. And you have to pay cash and no receipts or paperwork. And trailering it will def work.
I had him do three of my four f150's with a 5.4. Never had one leak. My exhaust was always tight, never rattled. He is top notch. He also installed 02 spacers when cats were cut off to keep the engine light off. Those always performed flawlessly. Only a couple bucks for each one too. I do not recommend cutting all the cats off. Leave two on. Trucks are ridiculously loud with all removed.
I got mine done in a town just south of me. Paid him 300 cash and watched him do it. Another shop said well thats illegal we wont do it, and itll cost 600 for us to run new pipes if boss allows me to. Haha
