This is the single collected race header from RB. It was sprayed with ceramic coating only on the outside. Entertaining interest as it is still on the car at the moment (daily driver). Changing my build plans and have no use for an NA header. $120 for whoever wants it...

 

ahh haa interesting hehe ive seen this header in person and is mint... bump for my boy

 

What does this fit?

 

13b rotary engine. Im sure you cut cut the flange off where it bolts to the block and fab it up for something else if you want.... ( i wouldnt tho) but its designed for a 13b engine.

 

do you need the rb presilencer to be able to bolt it up to a cat back?

 

Im not running the RB pre silencer... lol.... otherwise i would be selling it as well. My setup right now consists of the RB header (ceramic coated) vband clamped to a 2.5 inch pipe, run into an expansion chamber (2.5 - 3.5 - back to 2.5) out to an RB muffler.... No cats.... no pre silencer.... and quite a few of you have heard it... its not very loud... Picked up 10hp over stock after putting it on...
