:wavey:Hey guys, please help me out,I have a FA5 si and if i get a mugen midpipe, will it fit the OEM axleback? or will i have to get the muffler as well? I know and hear the dimensions of the mugen exhaust is bigger, but it is only a midpipe change and a muffler to handle the outlet will come later. What do you think? other option is considering the A'pexi NOIR catback. any good?
