Wales will run out at the Stade de France looking to seal a Guinness Six Nations Grand Slam after wins over Ireland, Scotland, England and Italy.
Pivac knows a potential 2021 Championship clean sweep would be huge for everyone in Wales after a tough year hit by Covid-19.
“It would mean everything, really. I’m coming up to seven years in Wales. You understand what it means to the country and what it can do to productivity,” said Pivac.
“I noticed walking round the golf course yesterday on our day off the amount of people that were saying good luck for the weekend. They are very supportive.
“That changes very quickly from the autumn to now. We understand what it can do to people and we will certainly give it our best shot to try to get the ultimate prize.
“We get a lot of support from here in Wales, from New Zealand, and from all over the place. You’d be surprised where people end up and are sending messages from.
“There is a lot of support for this Welsh team and not only in Wales, I can assure you of that.”

Pivac continued: “I’ve been very, very pleased with what we’ve done so far.
“You want to win things – that’s what we’re here for, but it’s also about how you develop rugby players, watch them improve, and see them become the best they can be.
“We’re starting to see young fellas develop like Louis Rees-Zammit who has gone from not playing in the Six Nations last year to where he is now. Seeing that growth is just fantastic.
“It’s worth its weight in gold. Winning the Grand Slam would be fantastic and winning the Championship would be fantastic. If we end up finishing second it would be a big improvement.
“I’ve been very impressed with the players. Ultimately, they are the ones who pull the jersey on and go out there and they’re the ones that throw themselves into some dark places.
“Our job is just to get them ready to go and hopefully we’ve done a good job. We know where we have to improve and we know the improvements we’ve made.
“We are in a pretty good space, but we are not the finished article.
“And we know France are a very, very good side and if you look at the improvements we have made, you’ve just got to look at the French team since the World Cup. They’ve done a fantastic job.
“So it’s two teams that are starting to play some really good rugby and it makes for a mouth-watering final match.”
Pivac has made one change to his starting XV for France with Adam Beard coming in for Cory Hill to start at lock. Hill drops to the bench where there are also a handful of changes.
Nicky Smith, James Botham and Tomos Williams are also in the matchday 23.
Wales have 14 of their starting XV with previous experience of winning a Six Nations Grand Slam – the only player who hasn’t is wing Rees-Zammit.
There are 987 caps of experience in the Welsh starting XV which is a new record.

Galthie’s France are wary of the threat posed by Wales.
He said: “This Wales team won the 2019 Six Nations and they lost in the World Cup semi-final. Today they represent the leaders in this competition for now.
“They have a strong culture and of course a monstrous amount of collective experience. They have an average of more than 60 caps per player and an average age of 30-years-old.
“They are competitors and they know how to prepare. They know how to bounce back because their tournament last year was very difficult. Until Saturday they’re on top of the table.”
