cracked my B16As header, I need something I can just bolt right on, will an real ITR just bolt right on? if not what is the best option?

 

In short yes it will. It will not bolt up to the cat though. If you need a decent header for cheap that will bolt right up 100% look into some of the better headers on Ebay.

 

What is a better header on ebay, I've seen alot of this yonaka brand but people say you have to drill out the holes so ill probabley pay someone to do it, at that point its the cost of an itr that I could just bolt on myself or no? People say ill need an omni test pipe to make it work and it adds a little power but carboy says I can just buy an adapter for 30

Anyone have any input, a link to a good ebay listing or reputable shop would be great.

 

Hytech and Toda rep headers. I have a 421 header off Ebay but I have no idea who makes it and it fits perfectly and made power. If I could do it again I would have gotten a Hytech rep header. I plan to go turbo so no point in spending money again on a header. Having a test pipe with slip flanges is nice because it will fit any header and exhaust combo.
Here are some good header at a good price

All will work on a B16

 

if you get a usdm itr exhaust manifold yes it will bolt on to the head and meet up to the cat, the jdm itr header will bolt to the head but not to the cat, it is longer then a us header
