I've got a 1990 E-350 7.3L IDI.
The other day I took a 4" muffler off a Fire Truck and grabbed some extra 3" pipe lying around the yard.
I want to have the two pipes coming off the manifolds merge into a 3" pipe and then open up to the 4" muffler and follow that with 4" pipe to the back. The factory exhaust is 2.5" right now.
This will be a good test of my welding skills.
Anyone have any good info about what this'll do to the performance/efficency? I've heard a lot of opinions but nothing concrete...i've decided to just try it.
Some people say it will screw things up, others say it'll be awesome, i don't know what to believe. I'm going to clock my MPG and i'm also going to floor it and time myself going up a hill, then do it again after i switch it to see what changes...power or efficiency or both.
Lets see if you guys can beat all the BS i've heard from my engineering friends.
