So who has the best hi-flow cats...exhaust kit...and headers for a 05 G35 Coupe? It is between HP and sound and passing emissions as well too if someone wanted to buy a kit!

There is no definitive "best" for those parts. It all depends on your budget, taste, and what you're looking for. Search and do some reading to find out what's "best" for you.

Berk, and Fast Intentions are the most common brands for HFC's.

Lots of brands for exhuast systems and headers, all depends which one you like.
