if its for a b series motor, ive seen good numbers made off the 4-1 jdm type r stainless knock off headers. not sure what motor ur putting it on, but hell not all ebay headers are that bad. megan makes good headers, and if youre worried about durability, let me put it this way: i cracked a pretty good reputable companies header in a few different places before i ever did any major damage to the egay knock off i had origionally.
