7.3 Exhaust options

[Cdaley403]

I’m hoping to do a 4” exhaust and seeing a lot of straight pipe options but am looking for an option that deleted the cats but still has a muffler. What are y’all running. The only thing from MBRP I’m seeing is either a straight pipe or a cat included system.

Thanks!

Cat? You mean muffler?

I think they are refering to a cat back system. All they can find is either a cat back or strait pipe exhaust.

They want a catless exhaust but with a muffler.

To the OP, I generally buy a strait pipe exhaust then buy the muffler I want.

I put a Flow Pro 4" turbo back Stainless system on my old 97 crew cab a couple years ago after the MBRP aluminized system rotted out. The down pipe was a little tight and took a little fiddling to get it in the right spot so it didn't rattle, but so far so good.

99 should be able to use the sd exhaust, with a 4" dp.

Just delete cat with piece of 3.5" pipe, put in a 3" down pipe. The stock muffler is straight through. I guess you cant buy the "cat test pipes" anymore?
