Toulouse welcomed back more of their World Cup stars and raced to a huge lead but were made to sweat by last-place Perpignan before winning 43-34 in the Top 14 on Saturday.
Italian star Ange Capuozzo touched down for the home team after 19 minutes.
France's Anthony Jelonch, on his first appearance since the World Cup, added a second. Another France international, Melvyn Jaminet, Wallaby Richie Arnold and Paul Costes, also touched down in the first half for Toulouse.
Thomas Ramos, playing in his first game since having a conversion blocked as France were eliminated by one point by South Africa in the World Cup quarterfinal, booted 11 points as the hosts led 31-6 at halftime.
He was replaced by France's World Cup captain Antoine Dupont, after 47 minutes as Toulouse wobbled.
Perpignan scored with two tries in the first nine minutes of the second half.
Samoan World Cup player Charlie Faumuina responded in the 50th minute for Toulouse.
Perpignan centre Alivereti Duguivalu received a yellow for elbowing Dupont, who suffered a broken cheekbone during the World Cup.
But with 14 men the visitors scored twice in next seven minutes, through Mathieu Acebes and Sadek Deghmache to cut the deficit to nine points.
Toulouse stiffened but could not score the try needed to regain a bonus point.
Scrum coach Virgile Lacombe suggested that the team lacked cohesion because they were working the World Cup players back into the line-up.
"We shipped 28 points in the second half and that's far too many," he said. "We need to work and spend time together."
Flanker Francois Cros confessed to mixed feelings as he made his first start since the World Cup.
"It's a win that leaves us with some regrets, because we probably lost a point," he said.
"I'm very happy to have been able to play again with Toulouse to get rid of the disappointment of the World Cup."
