I heard a few weeks ago that J's had a new header for the 2.2 and now some people say it is the same as the 2.0 header. Is this true???

 

Mugen's Japanese site also has a new 2.2L header listed. I'd like to know more about it as well as the Js

Same header.

 

The newer version of the J's header has been changed a little bit. They offered that version for F20 & F22 engines.

 

But there is a difference between a F20 and F22 engine, right ?

Most of my tuning has been with motorcycles and it has always been my rule tochange the CAI, headers, exhaust AND ECU to get the full benefits.

Will you say that is the same with the S2000 ?

 

Am surprised! Can you post some pictures of the new version. I have the following version pictured below.

 

whats the difference?

i was just going to put my ap1 amuse header on my new ap2...

 

Built specifically for the 2.2L F22 engine found in the 2004 and up Honda S2000. Features full stainless steel construction and revised dimensions for the larger 2.2L displacement. Primaries are 50mm shorter, and secondaries are 50mm longer. Torque and horsepower gains are seen over the entire RPM range,

This is a quote from Kings website
Logic says if you change the motor internally, the exhaust from a previous generation may not work as efficently as one designed for the current generation
So if Mugen changed it, you know every other top end Japanese tuner will do the same.
I am not trying to debate who is better, but EVERY tuner in Japan copies Mugen. J's did, because they loved the Mugen parts. I dont blame them at all. J's still needs to make a J's hardtop

 

I know that J's Racing first build their bigger in diameter headers. This is known by anyone on the board and not only.
