It's not simple to construct low-run performance parts by hand and get consistent output unless the jigs are of a very high quality, and substantial time is invested in both design and manufacturing to ensure that the parts will fit appropriately - especially when large temperature swings are involved.

Anyway, just one person's opinion, but "you get what you pay for" is often true.
The headers you have are NOT the same as the Megan racing ones. I attached an image below of what you're comparing. Welds are different and the flange appears to be different as well. I read every post that goes into this thread on m3fourm about these headers and not one person has had an issue with the headers leaking due to improper fitment.

Any skeptical people feel free to go through every post on this thread http://www.m3forum.net/m3forum/showt...5&page=110

Until someone actually has an issue with these specific Megan headers leaking there's no evidence that these headers have issues. Lots of guys are tracking their m3's regularly with these on m3forum.

installed mine with OEM hardware today. Perfect fit. No CEL...yet. Im running DKF section 1 with resonators, stock x pipe and RPi mufflers. Fumes are quite strong though, might consider putting 100cell cats in. No tune yet...but car feels like it revs more freely than before from 3-5k rpm..very happy with the purchase.

I can confirm these fit with no issues. What a great bang for your buck

However got massive drone now with top closed. Thankfully it's almost always down. Top down is awesome and no problems. Kinda wanna go louder but can't tolerate any more drone with top closed lol

That explains it, changing section 3 (mufflers) will cause the most drastic changes in tone and induce drone from my experience. Just headers alone shouldn't have any drone.

Stromungs are not even aggressive mufflers though. So what you're saying is there's no way to go loud without drone? loll

With my experience on the roadster, changing the stock mufflers will usually have some sort of drone/resonance. I know a few of the mufflers are pretty tame and usually won't cause any drastic difference, but adding a cat less setup will increase rasp and overall loudness.
