i'm trying to find a good performance header for a 95 honda civic SiR. does anybody have any suggestions as to where to order one?

DC 4-1 and eBay or almost any website

 

do a search on yahoo or something. DC, Chikara... there are a bunch of companies that sell decent headers...

 

JDM ITR 4-1 with 2.5 collector h:

 

are you in canada? If so you still have the D series I believe, which means good header choice is limited, I think bisimoto makes a d series NA header that is awesome, but other than that there isn't much.

If you have an SIR anywhere else you should have a B series, which means any of the major header manufactures work good. make sure you get a 2.5" collector. The JDM ITR header is great for the price, if you have cash get a custom one like Hytech etc..

 

is the 4-1 better than the 4-2-1 as far as performance goes?

i believe 4-2-1 is better for low-mid range power and 4-1 is better for mid-high range power.

DC is fine but check out an-r.com
