Well been meaning to do this test for a while now. I was able to get ahold of a real Bisi header thanks to Martin (zuptidi) and a logic motorsports tri y thanks to Function. I'll post more information as the questions come in, but each header was tested back to back, same day. A/f was tuned on each one. I'll let the video speak for itself.

Header had the exact same characteristics as all the bisi header'd dyno graphs ive seen(garb midrange). Piece of ****. Inb4imanengineer.

zuptidi

the mid range is what people should see

nice video man. Its interesting that the Logic makes the most power, but is the least expensive.

The results are all real close though. All of these headers are good quality. Also, Other factors such as heat and whatever else can play a role here. I personally own a Bisi, and it fits and performs pretty nice. Im very happy with it.

Props to all of these manufacturers, and the video maker.

Good post Jaywest!! Wish I lived in the US, id sent you my header too.

wolve

pretty close all three

logic vs RMF curve is excactly what you'd expect. would've expected the RMF curve to keep climbing longer tough ...

very interesting video buddy. I dont remember your on 85 right? Was all this with full exhaust of just burns collector at the end?

Good job on the education lesson

JayWest

lol, cry me a river

yup on e85
no exhaust, each one was open header. none of them have burns collectors

btw, didnt get a chance to say wasup to you in jersey but i did make sure to snap a few pics of your car going down the track, ill pm them to you when i get a chance to upload them

SteelcityLude

nice. this confirms my decision

crazes

oh ok I going to be switching to 85 this weekend and see what happens with my setup. If there is time I might have randy tune a lil open header and see what the beast does. For sure the test was very interesting on how you have it setup and the fan facing right it the v stack. I might at look at doing this possible also.

Yea man I was asking and everyone he just left from here. I was like damnit that sucks.

thanks man if you get a chance send them to me. I have very few pics of my car or videos down the track would be nice to see what it looks like

Great video JayWest! Thanks for sharing your unbiased results with the forum. It's no wonder we can barely keep our new version 2 H22/H2B series header's on the shelf. Thank you from the Logicmotorsports.com team!

Do you the TQ #'s??

GoldLudeRay

thanks for sharing... and it goes too show that bisi's header is damn good thats for sure...but for a header claiming too be a custom made too modification's piece it isnt that great...the shelf logic is defentially kicking ***...i know my next header purschase...also a new vibrant header in the testing could be cool as well for the next h22 dyno session

dirtyharryhatch

Last thing we established was bisi's header's aren't custom.

The logic header yields the highest power gains, best ground clearance, and is the best bang for the buck! At under $400 bucks shipped, you really can't lose...

BTW those are stout numbers for your lude. Got any pics of that beast? Love the spray!
