What do you disagree?
HFC DO make extra 20 hp and axle back does not
HFC xpipe is high pitched and raspy and sounds extremely similar to the innotech f1
It is 5k cheaper
So if you do not need a valve than explain what it is you are in such disagreement of? I hear the innotech on a weekly basis as my friend has this setup. Our cars sound very similar with my HFC xpipe sounding a bit more raw but virtually the same.
