i can get this header for 500. thing is i don't know how long i have, so please reply asap.
1. is this header full radiator friendly or half size it is?
2. is cutting a chunk out of the front crossmember necessary or can i just do that little lip cut and bend?
3. ive heard the quality of these welds are trash and theyre made in china. is this true?
4. dyno results say there not worth the money when hytech reps smashed showe 2 less whp then the real bisi's. does it depend build the hp gains? i have a b18c1 with AEBS intake mani, Whale dick intake, and cams. stock everything else.

 

From what I've read, v2 loses a lot of midrange. There is a replica on ebay that is just as good.

There is a couple threads that show bisi's scripted responses and lack of defence on the subject. Dyno compared a hytech, ebay replica, and bisi. Hytech was the best performer. Bisi's was the same as the ebay one.

Research is truly key.

 

yeai read the samething but seeing if there was any different results.

If the welds are all finished.... But then again $500.. Damn.

 

The Bisimoto header will require a half size radiator and for the EF chassis with factory crossmember will require notching a little to accommodate the down pipe.

Bisimoto headers are still and have always been designed and fabricated here in Southern California. There are many speaking ill to detract people from the actual truth...

HP gains does depend on your setup and tune. If you take a moment to check out different youtube videos, and other folk with Bisimoto headers and you will see real world results.

Everyone understands your contributions and appreciates it but there's no need to continually lie about it. Apple puts "Designed in California" on their products but they are all made with Chinese and Korean parts. I'm gonna go ahead and put that link in my signature to get some awareness out there then...

Also what's the deal with the massive midrange loss?

^come on, don't mess up the man's thread

 

After looking at the Bisi header compared to the knockoff Bisi header, I say get the knockoff ebay one. Better welds, and waaaay cheaper.
