Muffler Delete Straight Talk!
I have an 05 F250, stock with the exception of the intake, and am looking to do a muffler delete pipe, not cat. My concern is interior noise while on the highway at highway speeds (2000rpms). I dont want to deal with any "droning" sounds for hours at a time. For those that have done the swap is this a concern? Or will I not notice any increase in sound while on the highway? We do a lot of highway driving and I will not do the swap if the noise increase is significant.

How much of a mileage gain? Is there any, even a slight, gain in turbo whistle with the muffler removed?

I would think with the sheer size and likely restriciton from the stocker the truck would breathe better and get better mpg without it.
So no big change in sound when on the highway?

You won't notice any sound change inside. I even removed it on my old excursion and it didn't change the inside sound. My current F250 has a 5 inch cat back and it has WAY more drone than my X did without a muffler.
Go for it, you won't be sorry.

I gutted the cat and welded in a 3.5 half inch pipe in place of the stock muffler. No diffrence in sound at cruising speed or in cab. Sounds really good at around 2300 RPMS and up. I got a little better MPG about a mile more
