I believe mclare has oem tri-y cast manifolds only.
You might want to check with him (Mclare). He has AMG headers listed under his upgrades and has mentioned many times that they are AMG:
"Okay, since this is what this thread is about and I have been bombarded with questions about what all I have done to my car, here goes:
This is a partial list off the top of my head. I will revise if I think of anything else:
ON HAND READY TO INSTALL
• AMG Exhaust system with new AMG Chrome tips and German Free Flow Cats (Thanks Justinwrock you wrock!)
• AMG Tri-Wye Headers (Thanks xtcbytes!)
• New Factory MB Phone Console
All work has been performed by me save the front end and removing the freeze plug and motor mounts.
And the list keeps growing..... I have had this car exactly 1 year this week.
Like Cascade says.. "IT NEVER ENDS"
