I've been lookin at these headers for a while now, read some reviews on em and they look like exactly what I need. But i did read a few people that bought these off ebay didn't get what was advertised and I wanted to make sure that these were the right ones for my truck..They're goin on a 01 5.3 z71. I hope they don't need much work on them to fit around the driveshaft, some get lucky and others don't from what i've seen. Also I'd like to know where the gains are with these headers on a single 3" exhaust? down low, up high, or all around greatness?

Those look exactly like the ones I received. Mine vibrate on the front drive shaft a little but only under partial throttle. Other then that they fit well. I can't help you with any number gains. Also noticed that the price went up on these. I paid 300 shipped for mine.

yeah price has jumped up a lot from what i've read other members got them for.. but a majority of people have had better luck fitment wise with these than the cal speeds on a 4x4 truck so I plan to run these. I just don't want to get stuck with 500 bucks worth of headers and not be able to use them

You get what you pay for. If you want to take the gamble thats up to you. According to the add they are for your truck.......

I understand that..but i've read a whole lot of reviews on these and about 98% are nothin but good things comin from these and the 2% are just sayin that it barely knicks the drive shaft and that you need header wrap on the spark plug wires so I think that's a gamble to take..i'll find out soon enough I guess
