After a quick E-bay search. It was easy to find these extractors.

Has anyone tried a set of these (or similar) on the auto & if so. What benifits did you get.......??

that = maybe a few hp, maybe and a lot louder.

i haven heard anything good about the obx stuff on the internet

 

I've heard the OBX header isn't really worth it. FYI.

 

OBX= Online Buyers XshitX
heard their exhaust is ok for the $$$ but beyond that I wouldnt trust their products really no real hardcore rep behind 'em. I believe most have stated that most of the headers out now for our babies dont do much if anything at all for HP or flow. If you wish to try 'em out please do so and give us your input, who knows I could be completely wrong

 

This item was discused in depth here https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/obx-rx8-header-73445/ and it didn't provide gains on a MT so expect none on a AT.
