OEM muffler??

[EK Devil]

I have a 2.25 straight pipe with a stock d series axle back so its going from 2.25 and out through 1.25 or whatever the stock d series axle back size is....my question is what muffler will fit on my ek hatch? gsr, si, rsx type s?

they'll all fit. just gotta cut and weld. but in your situation i'd suggest doing the rsx type s muffler with appropriate sized piping to the bpipe.
