Sup h-t's. I was wondering if anyone knew if the length of the profab header is the same length as one of the integra headers? Is is the same length as the 94-99 or the 00-01? or are they all the same and if so, what's the length of the stock headers? Need help to make test pipe. Thanks.

 

Pretty sure its a lot longer since its basically a copy of the SMSP.

They also recommend using a flew pipe.

 

I thought that it was the same. Does anyone have a measurement between the
header and the b-pipe? I have a 94 dx hatchback. I was thinking about putting a flex pipe between it instead of the cat. Just need the distance between the header and the start of the b-pipe.

 

look at the pictures here:

They're pretty long...

 

it is wayyyy longer, it actually replaces my cat altogether

 

Cool. thanks for the info guys.

 

oh yeah, also, do I have to flatten a part of the oil pan to prevent the header from hitting it? They said something about that because of the revised version or something like that. Anyone have pics?

 

Yeah you have to slightly bang in the oil pan with a hammer
