x-pipe for 4.8is?

[surreal]

I was just wondering what exactly are the benefits of the x-pipe...over say getting a dinan exhaust...i know the price is wildly different but other than that...which would you suggest?

if you add the xpipe it will be mildly louder.
It really depends how loud you want the exhaust to be. I know if you just throw straight pipes it will be really loud but i think their have been issues with rattles and maybe a loss of power. An x-pipe wont be as loud but still give you more sound than stock.
If It was my truck i would do the xpipe and see how i liked it. The pipe is like $80 and install around $60-80 . Good Luck

thank you krunk man....would you suggest magna flow x-pipe?

I believe thats what most poeple have. I think the 4.8 has thicker pipes so im not sure what size you need.

to my knowledge, running straight pipes without some sort of cross over is a very bad idea for engines that have two banks of cylinders:

you want to neutralize the pressure between the gases exiting both cylinder banks.

if you have straight pipes -- e.g., without any cross over -- the exhaust gases will not balance out. this could result in too high or too low of an exhaust gas pressure on the two sides of exhaust resulting in a potential DECREASE in power.
