I think the adage "you get what you pay for" fits here. They may work, they may require a little modification, but their quality will not be what you can get with mid-range, US made headers. I would recommend spending the extra $400+ and get a set of better headers.

I concur with the wise men here. DO NOT buy those. Stainless Power is the best way to get the best product at a reasonable price.

Notice the ONLY members talking trash about these headers, are members that have never actually used them!

I have Speed-Engineering headers. Perfect fit, finish, quality. 11 months, over 15,000 miles (daily driver). No squeaks, leaks, rattles, cracks or loosening.

I have off road pipes, reused stock bolts, new GM gaskets.

Also, If I opt for the off-road connection pipes, will that require fab work?

Just installed these on mine a month and a half ago, other than the crappy exhaust clamp they provided, everything else is exactly what it says...bolt on! No fitment issues. Just get yourself some nice 3"(2) band clamps for the collector. You can reuse the stock clamps that mount the stock exhaust to the cats

Had Speed Engineering headers myself. $355 shipped with off road connection pipes, O2 sensor extensions and free shipping. The build quality was excellent and fitment was super good.

Clamps that came with the headers look cheap, but I used them. Still on there.....

Like you, I used the two stock rear clamps, plus the two supplied clamps in the front. Just don't over torque.

Great headers for the price!!!!!!

Fitment seems to be the biggest issue....people don't seem to be debating performance numbers. The stainless grade is the same for most ....304.

In for "Well, there's CHINESE 304 and AMERICAN 304. If you don't pay $1300 for headers then you need to check your priorities."

At the end of the day, people run all kinds of ebay headers or equivalent (TSP). Good luck.

I have eBay headers right now. Only cost me $200. They work perfect no leaks. I was like you very skeptical when I got them for the simple fact I was in patient and I did not want to save money to get the ones I really wanted. But I am glad I got these. They fit perfect hand did everything the name brands do except for the label. Don't let anyone tell you they are crap. I've had mine on my car for over a year with no cracks no anything.

I agree if the 304 stainless tubing from china is good enough for the food grade industry then it's more then adequate for headers. It's getting harder to buy local products right across the buying experience. I like made in North American made but those choices are getting very rare.

Some things you "do right", like the wallet emptying nitrous setup I just bought. Things like headers, its stainless... and it fits... no brainer. I will likely give these a try also.
