NO IDEA...it started out as just a crack...i was told it woud be fine for a while....being the dumbass i am, i pinned it comin off a stop sign, and the truck jsut started screeamin and makin all this noise..had some nice blue flames comin out the bottom....not fun.
Where's the crack? I don't see how the mainfold just fell apart like that. As long as it has all of its bolts, and is still connected to the y-pipe, it should have been fine.
i have no idea either.. maybe something hit it and it cracked and jsut weakened over time, im not sure. You wouldnt think that would happen to cast iron though eh? I have no idea.
If you plan on doing a cam soon, then headers are really a supporting mod you need to be seriously looking at anyway. Same with the rest of your exhaust if it's stock.
yea i will call my dealership and ask em about the warranty...
i have a flowmaster right now..
how do you like your doug thorleys? how much gain did u experience with them?
PS
what does dumping exhaust do? everyone on here has done it and i dont know what it is...im assuming its when u saw it off under the truck?
whats the point of this? How does affect the sound of the truck?
just called the dealership....told me a cam swap wont affect my extended warranty unless the cam itself is the cause of any problems.....
woo heres a cam swap!

The stock pipes flow more than enough for a healthy cam. If he gets headers and replaces the factory y-pipe, the stock muffler is the only real restriction left. Don't replace the stock stainless pipe unless you really have to. :imo

I thought you were already set on getting them. I meant the rest of the exhaust system. Most people remove the 2.75" stainless pipe and replace it with 3" aluminized or unnecessary duals.
i remember when i first got this truck, i thought it had so much power..funny how things change after a while. hah
