Gutted cat or delete kit?

[pyro57]

Good day! I wanna get a little more sound (not volume/decibels) outta my 6.0. All is factory diam. exhaust pipe. So far I've just taken the factory muffler off. It improved the sound somewhat. I'm still under factory warranty, so don't wanna rock the boat too much... What difference has either gutting the cat and running straight from there (no muffler) done for ya'll, as far as performance/sound? Or just straight deleting the cat and running all straight pipe back, for that manner????

I say you should delete the cat and keep it so you can put it back on when you take it to the dealer for warranty issues.

Delete Kit, cats are expensive to replace.

I agree, go Cat Delete and keep your Cat in the garage just in case you need it down the road. They make a great conversation piece hanging up on the wall too!

Huh. Has anybody on here done that? And not done any other mods? Like airboxes, chips, etc??? How will the truck run w/ the cat and muffler deleted? Anybody done it yet???

You don't need any other mods. I removed mine and the truck whistles like a jet, and has more power.

i have a cat-back 5 inch MBRP, sounds great.. but then i went and took a saws-all to the cat and welded a pipe there, the ford dealership here said it was totally cool that it won't go against my warranty.. and now it has a sound that people literally miles away are calling me and telling me that they can hear me

I have 5" from the first bend after the downpipe, my truck actually went to ford yesterday and the tech working on it told me that on the 6.0 ford does not have any issues with aftermarket upgrades after the turbo. By the way it makes them sound like a jet taking off!

Yeah, I have a stock straight pipe, I just bought a 2' section of pipe a coupling, and a clamp. Just cut the pipe behind the cat and reuse the flare before the cat. Can be done fairly easily in the driveway.( Keep the penetrating lube and a pipe wrench nearby to get the new pipe into the flare though) The sound is great for the little money you'll spend. If you just have the muffler off now, the cat will make a huge difference in the sound of the whistle!
