After a few years saturated with struggle, Saints summoned up the ghosts of Christmas past to produce a performance that the title-winning crop of 2013/14 would have been proud of.
Let's get it right - they did it in a very different manner to how the double-winning team so often prevailed.
A strong set piece was the cornerstone of the success of four years ago, with the backs able to build from the scrum and lineout.
But with the scrum far from productive on this occasion, the backs had to elevate themselves to new levels of ruthlessness.
And they certainly did that, with Piers Francis, Dan Biggar, Fraser Dingwall and Cobus Reinach all so clinical when the chances came their way.
That is not to say the forwards did not play their part. They certainly did.
They managed to disrupt Exeter in the lineout on numerous occasions, preventing clean catches and stopping several drives towards the home line.
But it was in open play where Saints' big men really thrived, with their defence something to be really proud of.
Alan Dickens is an understated figure at Franklin's Gardens, even after his stint as interim boss last season, but the work he continues to do deserves real credit.
He has always known how to build a formidable defence - and he wasn't bad when he was in charge of the attack, either.
The determination that he, the other coaches and the fervour of the Franklin's Gardens faithful inspired was palpable.
There was so much drive in the contact area and so much ability with ball in hand.
In fact, if Saints had even got anywhere near to parity at the scrum, Exeter would have been out of the game well before their hosts went 10 points up with 17 minutes remaining.
The table-toppers looked set to turn the tables on Saints when they recovered from 14-0 and 21-14 down to level on two occasions.
But such is the belief that boss Chris Boyd is starting to instil in his players, they simply refused to be deterred.
Strong minds inspired strong bodies, and the black, green and gold wall that greeted the Chiefs on so many occasions was a joy to watch.
Saints were never behind in the game.
And they displayed the kind of resilience that top teams possess.
Fans are right to feel that though their side are only in their infancy when it comes to getting back to where they belong, things are certainly moving in the right direction under Boyd.
It always felt likely that Saints would lose games they expect to win, and win games they expected to lose.
And so it proved yet again as the roller-coaster nature of this exciting new era continued.
It will take time for these displays to become commonplace as Boyd continues to shape his squad mentally and physically.
And the fruits of his labours will not truly be known for a couple more years yet.
But what a start he has made.
Saints have placed big responsibility on the young shoulders of players such as Lewis Ludlam and Fraser Dingwall.
And they have delivered.
This win against Exeter was a statement success not only for the squad but specifically for those young guns.
They are here, and they're here to stay.
They will have watched on from the stands as Saints swept aside big sides on a regular basis a few years ago.
They will now look to produce more of the same in the years to come.
And if they can, these big Friday nights in front of sizeable crowds under the Franklin's Gardens lights will become the norm once again.
