which header will fit

[v4lu3s]

whats are the difference between all the prelude headers???? hhc5009 vs hhc5029??????

the hhc5029 makes more power as it has a 2.5 inch collector. a common thign is to buy the older model, hhc5009, and modify it with a 2.5 inch collector to uleash more power. DC got wise and dit it themselves.

does the the o2 sensor- bolt or reach to the dc header???? or do i have to modify???part #hhc5029 2.5 collector.

o2 sensor location is damn enarly the same as stock on the dc header compared to stock. Worst case you may need to weld a new flange onto teh exhaust but that is nothognt aht $25 cant fix. and that is worst case.
