Ok, I found Matrix Ceramic coated header for 175
and a arospeed Chrome header for 175.

Which of these would be better? Anyone have these? Do they just plane suck?, they couldnt be wors than a pacesetter.

Does anyone know the diameter of the main pipes, and the collector pipe on these headers by chance?

If I were you I would go with DC Sports Headers, they are the best out there right now, not to mention they come with a guarantee not to void the manufacturers warranty..

i was thinkin about getting headers too, but whats so good about dc? other than maybe being made with a lighter material, what can be different? not that it would matter anyways, since accords arent the lightest cars to begin with. im not certain, but if anything is better, i think the dc jdm's have a bigger outlet. but from what i heard they are not carb exempt.

also, what are the exact gains between 4-1 and 4-2-1?

and i think, unless protek got a certified used car, the warranty is probably void 10years later.

DC Has proven time and time again that they are the best. Dyno's prove it and racers prove it. I know that I was thinking about other brands of headers for my accord, but I figured I would rather spend the extra money and get something that has proven to be better. Them people at DC only make stuff for Honda and Acura, they know what they are doing. Having a full DC Headers\Catback system, I would not have gone with anything else, It sounds great and I get a considerable amount of added power. Thats just my opinion!
