Thrush Mufflers
 

Just bought a cheap 20 dollar thrush turbo muffler to put on the 6.9L. It's not a glass pack, it actually probably for gas engines. Will the side-center, inlet-outlet be a problem with a diesel? On past gasoline trucks I used these mufflers and never had a problem. I am just a little concerned about installing this one because all of the diesel muffler's I see are straight thru.

i wouldnt think so, i had a flowmaster on mine an had no problems

Oh okay, Thanks. They're basically the same thing.

yea i run a flowmaster on mine and i have no issues, you just want a good flowing muffler, dynomax, flowmaster etc,
