I was wondering if a mugen header would fit on a gsr motor? i heard that the bolt pattern is not the same so it would not work. But some people run Jdm itr or Dc jdm 4-1 header on gsr. Not absolutely positive, so i'm asking before i buy the header.

Thanx for your help.

 

exhaust man. bolt pattern on b-series is all the same, evn non-vtec's....so yeah it'll fit

 

jsut backin him up..it will fit
