I have a "Redhots" muffler on my 6.9, its a straight -through muffler, looks like a firecracker and sounds real nice, I think I even gained a few horses with it!!
Magic
Ive got an 84 F350 4x4 with a 6.9L diesel. I have been lookin forever for somone that makes headers for it with no luck?. I am wanting to mount straight pipes on it anyone no how good they sound? i was thinkin 2 and a half or bigger. My grandpa owns a gmc with a 6.2L diesel with straight pipes so i am wondering how my 6.9L would sound as good ?
I wish I could find a muffler that was so quiet I can hear a pin drop.
The stock muffler is pretty quite but am wondering if there is an after market muffler that is quieter.
I have twin stacks that come up through the bed, right behind the crewcab, and I'd LOVE to quiet my truck down just enough so that my wife can listen to the radio...lol
Have no idea what mufflers are on it, but I know they ain't doin much
