If the HKS was cheaper, I would've order that instead of F.I. Don't take this the wrong way though. It was one of the first I heard and personally, I love the look of the cans on it plus the burnt tips. But F.I is just as good, if not better, and still looks and sounds amazing. If Tony gave the option of adding burnt tips, then for me, F.I would have no competition. Hint hint
