Which header setup is better?,4-2 or 4-1. I need to know for my Z6Rex. Thanks

 

i think the 4-1 dc 1 piece...

 

From what i understand...

4-2-1 = midrange power (little more torque I think)

4-1 = top end power (little more Hp up top)

Pretty sure about that, hope someone can back me on that or correct me if i'm wrong. But mines a 4-1, i'd driven simliar civics with 4-2-1 and i'd take either one really. Its your pick hehe.

 

what habib says is right.

the 4-1 header will give you more HP higher up in the RPM's and the 4-2-1 will give you more mid-range torque. but i'm sure that the difference between the two is not that noticeable so either one would be fine.

 

who cares. buy whatever you can find cheap.

so you get a whole whopping 2-3 more hp if you use the 4-1 over the 421. is that 2-3 hp really worth your ground clearance.

a tubular header is a tubular header. it's all about the build quality and how long it'll last if you ask me. any tubular header is better and will flow better than a stock cast design.

 

4-2-1 is the best if you drive most of the time on the street

 

Wat they all say is true but i personally like the 4-1. Specially Stainless. Bling Bling. Looks meaner to me. But yah get what is cheapest.

 

Also i thing for the 4-1 you need more clearance in the crossmember and you might have to grind part of the xmember away. and 4-1 needs a little more ground clearance. Lots of my friends dent up their 4-1 pretty quickly. you might have to raise your car a little but i might be wrong. Depends on the type you get though, i think.

 

I was told from a Honda tech that the Stock honda header is best to stay with, but that was coming from a Honda dealer, he told me that the stock ones are tuned the best......
