that's where the comment "all other issues aside" originates from.

not 100% of things that come from China are done using slave labor, horrendous environmental standards, or using stolen IP. but the odds are high enough they are, I understand trying not to purchase anything from china, I do the same.

"setting aside the slave labor, genocide, destruction of the environment, aggressive threatening of other nations with nukes, and anti competitive behavior"

They have some top notch slave labor-- unrivaled labor prices in modern times.

Oh damn lol

all other issues aside, if the customer requests tight tolerances and a quality product, china can produce it.

... I work for a company that orders many parts from China (happily we're moving off that, finally). Bent and welded metal parts, so pretty relevant. Across suppliers, the experience is consistent-- everything starts out built to spec, and then drifts, when they think you are no longer paying attention. If you're Apple, sending 50 employees per day to/from China for QA, you can stay on top of them. If you're a normal company, far less likely you'll get as consistent of results.

Top China.

I seem to remember that the CPIs underperformed expectations power wise on the dyno, but the construction and fit was generally well received.

They did fit better than my SSv1s. Had to fight with the SSv1s a bit to get them on the studs, the CPIs just slid on.

He does carry Supersprint stepped headers, and has a BMW wholesale account though I'm not sure what his margins are. But you are right, his motives are certainly obvious. I don't understand why he would knowingly design, and continue to sell one of the worst catless header designs out there, however. Everyone I know who has them hasn't had any complaints--though I was primarily concerned with fitment. Is there a thread I'm missing out on? Easy to shit talk about a product on the forums, but how much empirical evidence is there? Back-to-back dyno sheets? Perhaps I'll make more of an effort to grab Euro headers.

I should say, he can sell the SS’s, after buying them from his competitor— ECS.

Jack “designed” the CPIs. Bimmerworld bought custom performance’s line when they closed shop.

There was several before/after comparison dynos on m3forum. That forum going down means we no longer have access to them.

[Tbonem3]

He didn't design it, Jack did, a long time ago. "Design" might even be too strong of a word.

Gawdamn newbs.

James clay owns the CPI header design and can’t source supersprint or sell OE for a significant profit. His motives are clear.

The dislike is because they’re worse than other options out there, including options that are cheaper than them.

I don't know who james clay is but it doesn't sound like he knows what he's talking about.

Races IMSA, GT4...owns Bimmerworld. Has built one or two E46s in his lifetime.

I'd rather get the stepped headers over OE if I'm spending $1,000+ regardless. Definitely keeping my eyes open for another used set locally...I got my last set for $500 shipped. Pretty hard to beat that value-wise. I don't get the hate towards CPI headers though; is there a big exposé thread I'm missing out on? Lots of back to back dyno comparisons showing that they suck? I generally take James Clay's advice on matters pertaining to M3s.

Havent had a chance yet, was about to get a HTE dyno tune but then the car was rearended. Currently, in the process of finishing up my new M3 build but it will probably have a supercharger by the time I get an HTE dyno tune.

Aww man you're that dude, sorry about that. Hopefully you get it done up how you want it real soon.
