Anyone have this header or know of anyone who does on ITR?

Wondering about your/there experiences & butt-dyno power gains.I'm wondering how it would compare to the T1R header.

Thanks.

 

No ones got this exhaust?

 

Installed one on a ITR, the owner's butt dyno said he can feel the improvement over the JDM 4-1 he used to have (But we all know how accurate a butt dyno can be! ). I would say it's a good cheaper alternative to other expensive JDM 2.5" collector header out there, specially if you have a relatively stock set up.

 

Sadly, the butt dyno is relative to the money you spent. Unless there is a 10 hp spike somewhere, or a solid 5whp gain across the powerband, the butt dyno won't detect much.

 

links to specs or pics?

Thanks BlueR

By the looks of that pic I'll assume that they use a 2.5" collector on that header?

 

Correct

 

The butt dyno seems to react to the money you spend or the time it takes , I 've worked on cars forever and my butt dyno is always wrong.

 

What would be the difference between teh T1R header and the J's?

 

"There is a difference between Japanese CAT and U.S CAT. Currently J's racing headers are not desinged for U.S. Consequetly, we only sell J's racing headers as a racing set up where CAT is replaced by J's racing straight pipe and exhaust. "
