Diesel new guy exhaust question
 

I just bought a 93 f350 with a stock 7.3 IDI. i would like to cut out the muffler and just replace it with a piece of pipe to fill the gap essentially straight piping it with stock size pipe but i have read that i need to have a muffler due to backpressure? Can i do this or is there a certain size pipe that should be run? If i do this will it burn my valves? Will it help with mileage and power? Any info would be greatly appreciated being as im totally new to the diesel scene.

Only Down side will be...it'll then be loud as ****...:rocking:

3" is fine

:tu:

thats what i had on my truck for awhile. worked perfectly fine. i just took a piece of 3.5" pipe, cut inch or so lines at the ends and pipe clamped it to the stock exhaust. works like a charm but makes it 5-7 decibels louder,which is pretty noticeable. also note, i'd use some sort of exhaust puddy between the pipes when you install it or 99% of the time it will have some sort of leak and you will smell it in the cab if you let your truck warm up

there is no danger mine is fine
