CDM = Chinese Domestic Market

SSAutoChrome, XS Power, *.ebay, and anything else involving metal-work at insanely cheap prices is all CDM stuff. A lot of vendors/shops, whether they want to admit it or not, outsource a lot of their work to China to have items mass-produced for insanely cheap... then shipped and re-branded in the US under their name and sold for normal USDM prices to make a profit. Think that $800 turbo-back exhaust from vendor ABC is great quality and worth it? I bet China apreciates the $50 they received from making it.

Don't get me wrong... a lot of CDM stuff is actually pretty nice... especially in relation to the cost.
