The differences (at least the ones that non-mechanical people will notice), is the Ark has more of an Aggressive look (I love the dual cans peeking below the bumper)..however FI has nicer tips.



The sound... I posted a vid..and that is just the grip with stock cats/headers...and it sounds beautiful... very deep rumble.. very very very little drone at street speeds (nothing a few clicks of the radio wouldn't drown out)... when you gas it.. Everyone knows... and at Highway cruising..she runs silent unless you gas the hell out of it.



I might replace the Cats next (no emission here in FL) ..but need to find out the difference between resonated test pipes and HFC's ..unless they are the same thing.. I don't know... but I cant imagine the sound being much better than it already is.
