Open Headers

[Mangled03gmc]

it will run lean, but in reality it will be running rich as hell from the front o2's telling it to dump more fuel.

Yep..

Will more then likely foul your plugs out, but you can do it, I ran mine for a while, but def fouled plugs BAD

[QuikBlack06]

so he should remove his O2 sensors before the plugs get bad???

i heard ur motor losses compression is that true??? idk just heared?? lol

[danger_ranger83]

thats the second time ive heard that...im not the smartest but compression is made inside the motor i dont see how exhaust is gonna make you lose compression..but i might be wrong

Haha your all sad about it. Don't worry bro your new pipe will be here in a few days and everything will be fine =)

You do not lose compression, but do some back pressure..If the front 02's were a bit further up in the collector on more headers running them open would not be a issue, but since they are almost back at the end of it, it is getting a huge wiff of fresh air in there inturn dumping fuel..
