Cat delete questions
Have an 06 F350 and am thinking of deleting the cat. Two questions:
How much does it help lower (if any) EGTs if I keep the stock exhaust system?
Will it make the truck louder? I ask that because my 05 had a cat delete and it was noticeably louder at both idle and acceleration than my 06 and my wife's 04 Excursion. I kinda like the smooth quiet ride 😎
Thanks for the input

I was just going to get the muffler shop to cut out the cat and replace it with a piece of pipe. $60 bucks to do it

I pulled mine out and used a drill bit to drill it out then used a rod to beat the rest of it out. My delete was free. slightly louder. I have no idea egt as I dont have a gauge but my cat as blocked so it ran much better.

I wouldn't think there'd be any difference between an 05 and an 06 as far as sound goes. Unless of 'course your '05 had an AM muffler too...

Nope. Stock muffler on the 05.

When you say a little, is that like 20-30 degrees or like 100 degrees?

I've been debating between gutting the cat in my truck or just getting a cat delete pipe. With the delete pipe, I would have to swap it back and forth each year for emissions, but at the same time, I realize the OEM cat is around $2800 from Ford and if I end up moving to California, they only allow OEM cats. My fear if I gut the cat is failing emissions if I move to Cali. It would, however, make emissions in just about every other state more convenient.
I would also like to know the EGT difference after deleting just the cat.
