OBX is a rip off company. They mimic high quality/high dollar items with cheap knock offs. They look to be modeled off the RippMods heades, but those retail for around $850.

OBX = crap

just a note....it would probably be a good idea that you not buy performance parts off of ebay. most are just scams or generic parts. maybe some of the intakes are ok but other than that, most of it is crap
