Wassup guys , im looking at going with either the Motordyne HFC or the FI RHFC with my stock exhaust (for now). Now to my knowledge the MD HFCs are pretty new considering I have searched online and can’t find any sound clips , just a discussion on the 370z forums asking if anybody has heard them. For those of you that haven’t seen them i’ll include a pic in the post. Just wondering if anybody out there has heard them or if I should just go with the FI RHFC and call it a day considering there are plenty of people running those.
FI is high quality indeed. And everything that I have ever bought from MD is also high quality- dare I say I was more impressed with MDs quality than FI.
I think the real difference here is sound. FI's RHFC are resonated. I had those on my car. coupled with the stock exhaust was awesome for sound.
MDs HFCs- I beleive they are not resonated. So the sound will be louder and with the stock exhaust could produce some rasp at certain RPMs as would be the case with any HFC
