Will mugen header fit b18b motor without any modification. If not, what mods will need to be done? Thanks in advance

 

Um, if the header is for that car, then yes, it'll work...

Is it from a diff. car???

 

i cann only think of one mugen header hes talking about, and i know they fit bseries vtec heads, not too sure of ls motors.

 

The header is for a type r which has a b18c5 so I don't know what I would need to do, if anything, to make it fit my LS B18b motor.

 

wow, no one knows???

 

It will definitely fit on the LS block, but you will have to modify the flange bolting to the cat because the mugen header probably have a 2.5" flange.

 

so what if i run the Mugen header onto a Mugen exhaust?
Btw, how sure are you that the header will bolt right up to the LS block?

 

props to your header buddy i hope you get the info

 

the header itself will bolt onto the motor, the only thing you will have to do to make it fit is the bpipe or the cat depending if the header. the bpipe will either needed to be extended or shorten then also the flange might need to be changed also if the header flange is larger.

 

i was really hoping it was just plug and play

You will need a different catalytic converter. Is the Mugen exhaust (I assume twin loop) modified for USDM catalytic converters? King Motorsports did modify these to fit.

The header will bolt to the B18B head with no problems.
