i have a 95 RS with a drop in K&N
i wanted to get headers

are they worth the $ ? how much hp can i expect? which ones are better?

will i also need to upgrade the rest of the exhaust system to feel a diff????

thanx

 

First of all it's header, you only have one.

Second, they're all constructed differently and give different gains. I personally have no experience with any brand of header, except installing that $150 Chikara header on my friend's DX Civic, what a piece of junk that was.

 

a good 4 to 1 header such as a dc jdm(u could go w/ hytech,smsp,mugen,etc but not really necessary unless you have major n/a work) will give you good top end...you could lose a little bit on the bottom end but ive heard people argue about this before. i would recommend a dc jdm 4 to 1 w/ 2.5" cat.

 

if i get a ls/vtec head at some point will i need to get a different header or they will fit??
