Exhaust Question

[Bocephus_3349]

I have a 97 7.3 besides the DIY intake it is bone stock. What I am wondering is if i have the cat and muffler removed would it yield any advantages to performance/fuel consumption for me. Thank you

you will notice a difference with the cat removed, and you should get yourself a good down pipe as well, good luck and

ya the thing in the stock exhaust that really restricts is the downpipe, its flat as a pancake. thats what will really make a big difference, along with removing the cat and muffler.

I appreciate the responses thank you. I will first have them removed and work towards the new exhaust. I realize the downpipe is a major weak link in the system, but without replace it yet would you think that I might be able to notice or feel a difference with just removing the cat and muffler? I really fill like the truck at times is bogged down. Thank you again

I'd start with the downpipe. The further upstream you can reduce restriction, the more bang for the buck.

When you do a down pipe go with diamond eye a lot nicer then MBRP stuff suxs to install and looks like poop
