These look very similar to a set that came on my car when I bought it. They seemed OK and fit pretty good, but I ended up taking them off and replacing them with a set of the 1 7\8" Speed Engineering headers and it was a night and day difference for the better.
Never seen those ebay headers, but I'd spend a little more to get a set from Speed Engineering. They're a sponsor here, and plenty of guys here have been happy with them.

Speaking from personal experience I'd advise you to stay away from cheap off-brand ebay headers. I bought a set a few years ago figuring I could save some money and the fitment wouldn't be too bad, I was wrong. To say they fit like **** would be an understatement. As soon as I got the money up I got rid of them and purchased my LPP headers. Money well spent
Thank you guys for all the votes. Just an FYI for those reading, eBay headers are actually 1 5/8" primaries not 1 3/4". They try to hide it noting the inlet sizes are 1.75", but if you look closer the diameter is 1 5/8".
Thanks

Another vote for the Speed Engineering here too. I bought their 1-7/8" without emissions headers and they are excellent for the price. Fit perfect and the finish is very nice. A good friend of mine bought a set similar to the ones linked in the OP but for his single cab sierra and they didnt fit at all. We had to beat on the primaries, beat on one of the collectors, move both O2 sensor bungs and after that was all said and done, the flanges werent even flat so they leaked like crazy. Stay clear of the cheapies on eBay, because youll more than likely end up buying a second set of headers after you realize how garbage the first set is. Speed Engineering is the way to go to get a quality header and save a few bucks.
These were the first set of headers I purchased. I would not advise buying these as they primary is only 1 5/8 and they are very thin. So thin that it sounds like an exhaust leak in the cab. You can hear right through them and its not a good sound. Fitment was nice and they are shiny, but they are noisy.

Well 3 years ago when Speed Engineering came out with race version , I predicted that ebay header would fall in price. 3 years ago the ebay headers were selling for $180 range , now they are selling for $132 , one vender is selling for $100 and you pay $40 shipping. These are the same headers that they sold then, they have not corrected or improved in any way still 1 5/8 , still have fitment issues , still have O2 bunges on wrong side . And I think they will fall even more in price , whats amazing is that they can make these so cheap ,then ship over here for that cost. Buy the Speed Eng. headers well worth money .
$132 w free shipping is insane cheap. If I knew I wasnt going to go all out modding my car I would be rocking those headers. When you click that link you should see other sellers on ebay selling this header for same price and there are pics where they are measuring the tubes with a caliper and it reading 1.75" Some ebay headers I believe are now a full 1.75" primary.

Tophat ( or anybody that has direct comparison between 3/4-7/8 feel free to chime in) Is that all you changed was the headers and felt a decent difference? Debating going from 3/4 to 7/8. Have read tons and get 50/50 feedback on if it's worth it?

Another vote for Speed Engineering. I have bought 3 sets for myself for F-bodies. Probably 2 sets for work I was doing on other guys cars and 2 sets of truck headers for customers. Easy installs and great fit.
The full ORY kit for an F-body is great with a stock located or the BMR relocation Torque arm. Forget using a UMI relocated Tq Arm. Its doable but you won't be happy when your done
