Alright i have a DX 2001 civic got headers but it doesnt have the catalytic converter on it so is that a ex header and the exhaust i want is the HKS hi-power one so does the have a catalytic converter on it.?
i want the catalytic converter!

 

when did the 4cyls get headers??

Anyways...if your buying a header an downpipe most likely the cat will not be included. Need to ask the seller to be sure.
