The works manship on these headers is second to none they are perfect as far as welds and fab work goes. It will take me a little while to get them installed as I am waiting on a true dual exhaust and I still need O2 extenstions and sims plus these headers come with no hardware or gaskets. Iwill probably reuse the stock bolts if possible and go to GM and get a new set of Stainless gaskets.

 

I'm glad to see someone with the gonadulars to take a gamble on these... I've seen them on eBay for awhile now, just been too broke to get anything for the car.

Let us know how they fit when you get yer duals, bub.

 

can you please takes some pics like these:

thanks!

 

Slowscott how are these is this what you were looking for? If not let me know and I'll get waht you want.

 

I was gonna say the same thing. Those look VERY similar to my Pacesetter LT's. Those look really nice & look to have a decent flange also.

 

Yep! thanks alot they look great. Hopefully i'll be able to order some soon.

 

it doesnt look like you will need o2 extensions, seeing that the bungs are on the "inside"... just a thought, i could be wrong

 

i just bought the same ones off ebay for my 6.0. they fit great and only take about half hour to install since my motor was already out of the car. sound good to. i don't have a y pipe since i have tsp true duals.

 

Did the true duals bolt right up?

 

has anyone installed them in a car yet?

 

My Dad just bought a set. He should be installing them ina week or two and Ill definately let yall know how they are Damn good deal for $300. It sorta tell ya the markup on them.

 

I've been waiting for awhile now for someone with lots of tech cred to buy these.

Anyway you can tell if the flanges are stainless too? I read on another forum that ssautochrome headers dont have stainless flanges, but then again I'm not even sure how people know these are from ss autochrome.

 

What makes these any different from the older style of QTP's? Am I missing something here or just a $400 difference?

 

$400 means nothing to you?

 

At first, the 5/16" flange made me wonder, but then I remembered that stainless has a gazillion times higher yield strength than regular steel.

 

Thats what I mean, is that the only difference?

I did some research and they use 321 stainless compared to Kooks and QTP with 304 stainless.

321 has Titanium added to the composition and a greater heat range up to 900 Cel. I know exhaust doesnt get up there but it is used to fabricate jet engine exhaust manifolds according to some articles.

 

From the pics and description they look legit. I dont know about the 321 grade stainless, but id like to see how these handle the weather.

 

I see what you mean now, but I doubt anyone will buy these for any reason other than price.

321 should be less magnetic than 304, right? If someone had a pair of kooks or qtps and a pair of these they might be able to tell if they truly are a higher grade of stainless by using a magnet.

 

From what I understand stainless should not be very magnetic at all, I could be wrong someone please tell me if I am. Check this out:

http://www.azom.com/details.asp?ArticleID=965 = for 304
http://www.azom.com/details.asp?ArticleID=967 = for 321

I can understand that QTP's are more because of the velocity spike, HFMC, polishing, and simply the name. But I really want someone to get these on a car.

 

Good price..not good if they hang low like slp though....they look good..5/16 flange you say.??..hope they go in easy for you...
