"French teams love playing at home and they always put a real party on," said the former Bristol half-back who returns to England with Worcester next season.
"We have the trumpets and drums going and the whole town will be right behind us.
"It does sound like a cliché but support like that can act as the 16th man.
"It's a big bonus to train as normal, wake up in familiar surroundings and not have to travel but we all know that this is going to be a massive, massive game."
The 32-year-old former England International scored one try in five European outings for the French side this season and is looking to sign off his time across the channel in style but knows Munster will be provide a strong challenge.
"Munster are simply European giants," he added.
"They are a huge club and we know we have got a real challenge on our hands.
"They will bring over loads of supporters as well so the atmosphere in the stadium should be perfect.
"We have got two important Top 14 games before the quarter-final and we are hoping to do well and really build the mometumn before the fixture.
"Brive is such a small town, rugby is everything here. Shops close and match-day and the whole town has an interest in the sport and with Munster coming it is creating a real buzz around the place."
