idk man.... ive done mettallergy for a few yrs and if ya look on the inside of the DP that dont look like SS to me... and if ya look on the mountin plate theres rust forming around the welds.. rust will form on SS but not normaly (takes alota time)... only it it was sanded or if the weld are not right (used the wrong rod to weld with) or just a poopy job welding...

i did heat treating for almost 4 yrs... and ive seen alota metals and if this is a SS its a cheap type... to me it looks more like a moly then a stainless... but then agian i have been proven wrong

oh ya nad BTW the collector on the pacesetters is a 2-1 this is not like pacesetters version...

The header packaging was not too bad, shipping was fast.
Headers are 304 or 321 stainless (something non magnetic) The problem is that the flange is mild steel and will rust. Proof of this is me holding up a header with a magnet below.
1 5/8" primaries, 2.25" crossover and 3" exit. All 18 gauge. Flanges are 3/8"
Welding is average with some spots being very good to some spots being poor. There is a crack in the welding on a couple of primaries where they attach to the flange. I don't know if this will cause an issue or not.
The collector welding is poor with gobs of slag and filler as shown below.
They are not polished as shown on Ebay but that shouldn't affect performance.
The flex is single wall and similar to the other header flexes on the market.
We haven't installed them, so I can't give info on that yet. There are no instructions what-so-ever and no included gaskets or O2 extension.
Overall, I think the price is pretty good and I didn't expect anything more or less that what we received.

You get what you paid for.
Some of you may be thinking wtf is with mild steel flanges. Stainless expands and contracts significantly more than mild steel and with combuston temps happening close to the flange, it may lead to stretched bolts etc.
We are using mild steel for flanges on my buddies turbo log manis for this reason.
