I am thinking of getting the Hondata reflash and need to know the difference in size between the collector's on each of these. Please let me know. Thanks!

 

Sorry, I won't be able to answer your question.

But, I wanted to chime in and suggest that you look into getting the reflash a bit more. Many people have said it does nothing at all -- a complete waste of your money.

 

Moving to JDM forum

 

It would make most sense to use the Toda header since the reflash was optimally tuned to use that particular header in conjunction, as 2QYK4U can corroborate. A different header would not necessarily yield the same gains as suggested on Hondata's website, albeit they probably won't be too far off.

 

They are all 65mm approx. 2.5"

 

mugen 45-50.8-60.5
toda 45-50-55-60

both according to hyperrev

 

Thanks guys. I talked to the guys at hondata and they said the as long as the collector size is similar the gains should be similar since the Toda and Mugen header have similar designs. Thanks guys.
