Connacht ran riot at the Dexcom Stadium to demolish Montauban 75-14 and seal a place in the last 16 of the Challenge Cup.
The understrength French visitors were completely overwhelmed out west, shipping 11 tries on a chastening night.
Montauban actually started quite well, but once Paul Boyle galloped over in the eighth minute, the floodgates opened.
Cian Prendergast added a second try with 19 minutes gone, and though Montauban responded almost immediately through Jean Seux, Sam Gilbert's try and a penalty try ensured the bonus point was bagged before the half-hour mark.
Ru-Hann Greyling had received a 20-minute red card for a hit on Cathal Forde by that stage, and Montauban were floundering.
Harry West, Cian Prendergast, Matthew Devine and Boyle all crossed the line, with Gilbert's trusty boot ensuring the hosts led 56-7 at half-time.
The scores kept coming on the turnaround, albeit the frequency with which they arrived slowed down.
Sean Jansen, Shane Jennings and Dylan Tierney-Martin got in on the act, with Paul Valle getting Montauban's second try of the night in the closing stages.
