I have a 1990 f250 7.3 diesel and i was wondering if i get a cheap muffler and then cut it open and gut it how would it sound? Also would i get better fuel mileage? i dont want it too loud but loud enought to hear me coming a lil ways off. I live in North Carolina and you are required to run a muffler (For safety/emissions) so taking the muffler off wont be an option. Thanks for all of your openions.
i got a 2 inch cherrybomb on it now but you can hear the backpressure. loud but not good fuel mialage. I ordered a new muffler off of ebay. 3inch in duel 2.5in out. I might gut it but i dont know until i try it out.
Sounds like someone is trying to loose some friendly neighbors. My brother hollowed out his mufflers on his Chevy K-5 Blazer with a 350 and that thing was loud. I would drive it to the store and I got so many dirty looks but that was part of the fun.
