if it is determined to cause problem, yes... but same with any other after market mod... however, I doubt HFC would cause any warranty issues... just smog check problems.

Yeah I have asked a few people at my infiniti dealership and they all say something different. One guy said the only thing that will void warranty is headers, then another guy said I cant do anything other wise it will void my warranty, then finnaly another guy said that anything I do to the car and there is a problem as a direct result of the mod would void that part.

^^^ thats with HFC & Headers???... wow, quite tame actually... and a little thin. I'm not knocking it, but I figured with headers it would be much deeper. I have HFC without headers and its quite a bit deeper than that...

yeah, the clips don't really do it justice.

yeah, they never do... that’s why I never understand people requesting clips of exhausts when they are trying to determine which one they want... sound clips never sound like real life... I figure yours must sound quite a bit deeper in real life...

I just installed Berk cats. They definitely add a good bit of drone to my Fast Intentions catback. I did some measurements of the piping for those who are curious. OD is 60mm or about 2-3/8". ID is 2-1/8". For reference, the stock cat ID is 2".
