the stainless 4-2-1 headers off ebay are about $100 shipped brand new, with hardware and gaskets. They make as much as power as any name brand header such as DC sports because there made in the same sweatshop in china. its just differerent labels. I don't really care about brand names,

the coil overs in my car are no names but they look EXACTLY like SKUNK2's and my friends EG hatch has the real deal skunk's and both cars ride the same. both use kyb agx struts. He bought the JDM 4-1 type r header off ebay (ebay knock-off) for $150 and New England Dyno and tuning's dyno showed a 7.9whp increase with this header and 1.7wtq @ 6-8k rpm's. His hatch has a JDM obd-0 b16 swap with skunk2 IM.
