I have a 90' Integra with a B18B that I'm about to swap in. Well Ive owned this car for about 8 years now and the first thing I did when I got it was get a DC 4-2-1 header. Its very ugly and kinda looks like the stock headers do when you take them off after 10 years. Only reason you know its a DC is because it has the DC logo and carb # on it.

My question is, should I replace this header with a newer DC 4-2-1 header or just spend some time re-newing the old one?? Has DC's header design for the B series non-vtec changed at all in the last 8 years or so?? If not and the new ones are the same header I have now I think I should just clean it up and paint it.

 

Either way it should be ok, I think it would be much cheaper to just file the rust out and clean off the header. It might be wise to put some anticorrosive on the header after you clean it off tho

 

I was mostly just wondering if the actual design has changed at all in the past 10 years or so. Because if the header out now as the same as the one I got 8 years ago I would most definitely keep my header and fix it up. I know someone who does sandblasting so I would just have him clean it up and I could paint it with some sort of anti-corosive and then some high temp paint.

I know my header is old and just wasnt sure if the design has changed at all. I mean they had alot of time to improve on the design from back then.

 

Im pretty sure the header design has stayed the same from then, or was tweaked on areas not related to it fitting to the engine, so the new ones more or less should be just like the old ones. Flow might have been improved a little bit from ten years ago, but the design should be basically the same. Hope this helps

 

a good set of DC cost around $500-600 ... so y get new ones ?? the old ones are fine... jsut throw some rust remover on it and polish it

 

u can pick up a 4to1 2.5 inch jdm style dc for like $250 try ebay they always have a few for sale.
