I purchased the 18" res FI catback, as well as the HFC's from FI.

On my Nismo catback, I loved the growl the Berk HFC's gave the exhaust, but really hated the hiss as the RPM's would fall or driving through the neighborhood cold, before the pipes and everything really heated up. I had my friend drive my car past me and it sounded like *** when the pipes were cold. Eventually I sold the Berks because I couldn't stand the hiss.

So why have I purchased the HFC's for the FI? Well, I've watched both of Tony's videos a thousand times each (the original 12" and the 12" w/ HFC tunnel runs) and just LOVE the extra growl the HFC's give it. The thing sounds beautiful without them, mellow and exotic, but with the HFC's just downright mean. Tony's videos have convinced me to give the HFC's (the FI ones this time around) a second chance.

Mine ships this week, I intend on doing video of both with and without the HFC's installed. As before, if it turns out I don't like them, I'll turn around and sell them as previously. Either way, I'm confident the exhaust will sound badass.
