So I've been reading a lot about the MMW header for the tC, and im very nervous about purchasing, especially after seeing all the mixed reviews. This thread is going to be for tC owners who have/had the header installed. Can you please tell me what year your car is, when you ordered the header, and how the install went, and well as the overall experience dealing with the header? Thank you very much!

[loser responding to his own post...]
so i decided to go with alphaworks headers, and a DIY antifouler. However, i'll keep the thread open since it might be helpful to others...

I own it, love it, and only had one problem of it cracking but that was due to my driving. (I hit a dip REALLY hard and I suppose it caused it to crack.....but apparently it didn't show for months) Anyway, a week after the crack was found, the crack split completely appart. I mean, it was a clean, almost perfectly split crack right along where the pipe met with the joint. They had not welded the header all the way through. The weld was more for "appearance"....as I was told.
Anyway, other than that. I absolutely love the power throughout the entire band and many a shop tech have admired the quality and overall look.
I, however, got one of the first ones ever made. There have been revisions and it appears that many are having more issues with fitament for some reason. Some have even said that they have had issues fitting an OEM header on other cars.
I dunno, it's up to you

Thanks... I was about to jump on this MMW sale but decided to hold off untill other 4-2-1 headers are released such as Draxas or whoever else just for piece of mind. It is def. my next major mod. and I want to make the most informed decision possible.

Not only that, I don' t think there's an ETA on header either.
