Thanks for uploading the videos. Did you feel any power increase from your HFC install?
Any issues or negative side effect from installing HFC on you stock Nismo exhaust?

Anytime man, there was quite an obvious gain in power right after installing the HFCs. I can now tell how restrictive the stock cats are in comparison to the Berk cats. The car pulls stronger and exhaust now sounds throatier; it was way too quiet for my taste prior to the HFCs now things are where they should have been stock.

No issues or negatives to be reported whatsoever, the installer did a fantastic and sealed the joints to prevent funny noises. Once you get the cats installed, there might be a very low pitch hissing noise when taking your foot off the gas and with a cold engine. Mine went away once the cats were past their break in period. Dynamat in trunk & doors would eliminate any worries with noise. This is indeed one mod you won't regret my friend

Anytime man, I'm sure you'll enjoy the new exhaust note. You mentioned that you might go with a new exhaust as well, if so, the Fast Intentions exhausts are a huge hit on the forum. They sound mean and look great. I ordered one from Tony (Fast Intentions owner, great guy) and will be installing it in May (will post up update when it's on if you want to change your nismo catback then).
