So I'm thinking off bolting on some longtubes on my truck but need to know exactly what I need to do it right? I'm thinking of longtubes without cats straight into my borla muffler! Will I need a tune? Do I just bolt up the o2 sensers to the headers? Ill most likely be doing this myself except for the cutting and welding parts! Thanks guys!

I just did the Dynatech long tubes over the summer but with cats. Your stock 02 sensors should transfer over unless they come out with the threads ( i ended up replacing one) You definitely should get tuned afterwards. While in there, i would recommend changing the header bolts out to ARP studs and use OEM header gaskets.

Ok thanks for the info! Is a tune a must? Or can I drive it untuned for a while? Will I have check engine lights on?

Were you able to tell a noticeable difference with the addition of the headers?

Normally you probably could drive around for a little while but your check engine light will definitely be on. Being you are removing the cats, i am not sure how it would affect the drivability without a tune.

the truck feels a bit more powerful. Idling or cruising it sounds about the same, but when you mash the throttle the truck screams. ( Get a lot of compliments on the sound). Before the headers i was already tuned by Blackbear so i just had them retune for the headers. I am sure if you compared an untuned truck to a header install and tune it would be a lot more dramatic difference.
