I'm considering this header and was wondering if anyone has this header...opinions,dyno's etc.

 

I have it.

Few people on this board actually have this header due to the fact that it is not 'jdm'.

I was using the JDM 4-1 header, but i sold it for the JG. The JG header gives massive amounts of mid range over the jdm 4-1, and provides the same, if not more high end power. According to jeff, 16hp more midrange and 6hp more over the jdm 4-1. I say get it, awsome header

ps. i dont know how much jeff sells these headers for, so i cant help out on price, he just 'modded' it for me

 

as many threads as i see on this subject i figured at least one would be found in a search

 

true, i respond to one of these at least once a week.

 

What are the dimensions of the header (primary and secondary)? Thanks!

 

Was this before or after tuning of the modded JG header?

 

Thanks for your input...I did do a search and found only a few responses to this particular question from people with actual experience with them...any input is appreciated!

Hell if i know it just says that on his site

 

On ebay, it also says this header makes 20 whp over stock. I prefer dyno charts.

 

go check his site, you'll find dynos

 

I couldn't find any dynos for that header on the site. The only IB modded header dyno that I could find was an '01 Prelude that made 13 peak whp with an IB modded DC header, an unnamed exhaust, and Hondata tuning.

That almost looks like a Kamakazi header for JRSC
I don't see how its better than the JDM 4-1
dynos would be nice

 

It's not on a typeR motor though

The header pictured is NOT the JG header

 

Sorry, I didn't mean to give the impression that the header I posted was the IB modded JG header. It is one found on ebay that was discussed in another thread. My only point was that the ebay seller made claims about the power it made without providing any graphs to support it, and that I prefer to see actual graphs instead of statements such as "makes 15 whp."

IF i was selling something, yea i would understand, but im not selling anything. Someone asked for a opinion on the header and I gave him one. I have had both jdm and the jg header, and the jg is much better IN MY OPINION. Im not gonna go search thru mulitple pages to find a graph of something I already have. Call up Jeff, he has dynos.

 

My posts were in no way intended to be derogatory towards you or anyone else. I was simply stating that most people (in this forum anyway), including myself, prefer to see actual dyno proof rather than a statement that product X makes Y amount of power, and that sometimes such claims don't give the whole story.

 

i gained 10 whp midrange, 6 whp peak, 6 ftlbs tq

 

The prices on these headers range from the low $500 to the high $600 range for the ceramic to polished one's. How much will an IB modded one go for?

 

You can get it modified at most muffler shops. I'll take a pic of mine so you guys can see what you need to get done. It cost me $30

 

Anyone know where to get a good deal on a JG header?

 

Can you post your dyno sheet?

 

that dyno of the gsr is mine. I don't have my dyno with the stock header (reformatted the comp...dunno where i backed it up).
