I found this over at Hater-Tech, and I figured I'd share it with everyone here... it's a really good header comparison:

check it out, especially for those of you who haven't bought a header yet and are trying to decide what brand to go with.

 

nice find, just wish they had exact numbers on all the headers, and wish they woulda compared some of the generic ebay cheapo headers too woulda been interesting

 

no matter if they would have shown dyno's for all them or not the Bisimoto header will walk on damn near any streetable design from any company for a D/B/H series engine.

 

still missing the two most important ones though: megan racing and ebay.

 

the most important one is on there IMO

 

^which one is that?

 

bisimoto, it's expensive but worth it because you make good power with it and it is super hard to make good power with any bolt on on a d series. It outperforms $1200-$1500 headers

 

In D-series.org, it seems that most of the serious performance folk swear by the bisimoto header. others seem to find the Ebay header the best which makes me wonder how they even managed to type in an answer. but i haven't used the off-brands so i cannot say anything, just goin by the assumption that Ebay off brand=crap (OBX for example)

 

way to bring back a dead thread, koots.. jk man

anyway, I think the "ebay header ftw" mentality comes from the fact that the gains are just as good (maybe slightly lower than name-brand headers) as the expensive name brands, and they're only like $50. The only negative thing I constantly hear about ebay headers is that some of the welds aren't that great.

but Hedman Chikara headers ftw!

 

1 1/2 years and going strong with my ebay header lol jeez im ashamed and proud at the same time, but it'll be a turbo mani soon
