The supremely gifted No 8 has only recently recovered from a collarbone injury which kept him out of the Rugby World Cup in Japan.
All of the 29-year-old Faletau’s previous 72 Wales caps were won under Warren Gatland, but he is extremely excited to sample a new era under Pivac.
The Bath forward starts at the back of the scrum against Italy in Saturday’s Guinness Six Nations opener with Italy in Cardiff.
“I think so,” said Faletau when asked if Pivac’s style will be good for his game.
“The brand and style the Scarlets played when Wayne coached them to win the Guinness PRO12 is an exciting brand. I’m looking forward to fitting into that and playing some rugby.
“Warren gave me my first cap. It’s definitely different with the new guys and the style of play is noticeably different.
“I’m enjoying being coached by them and playing that style of rugby. They have been doing a lot on the basics of handling which has been good.
“Personally I can get a lot better at that. That’s what they’re driving and I can improve on.”
With a healthy choice of Welsh back-row options at Pivac’s disposal, Faletau has vowed to put his best foot forward in a bid to keep his starting jersey.
“It will be a step up this weekend as international rugby always is, but I’m just glad I’ve had a couple of games back with Bath to get into the swing of things,” said Faletau.
“I know of the strength of the back-row. It could be anyone picked on any given weekend.
“It is on me to have a crack this weekend. I am just glad to be out there playing rugby.
“We trained at Principality Stadium on Thursday and pulling in there brought a few nerves on. I’m sure there’ll be more on Saturday.”
