I have an authentic Mugen Header that was made for the EF9/EF8. It is a 4-2-1 2 piece and has the extremely rare weldless flange. This was made for a B16A but I have ran it on both my B18C and B20B. My B20 Made 196whp with this and a stock cat. I don't have a set price just seeing what offers are out there. This is one of only 3 that I have ever seen and the only one I have seen in the states.

 

How is the bottom.. Too bad it's a two piece.. I like a one piece... But for a right price, his would be nice..

The bottom has no dents and fits very tight to the pan just like a factory piece. This was originally designed for the 88-91 Civic/CRX SiR so it is extremly rare. It's a 2 piece so you don't have to unbolt the crossmember to install it.
