The two clubs will meet in an all-German affair at Wembley on Saturday, with Bayern keen to make amends for last year's defeat on penalties to Chelsea on their home ground of the Allianz Arena.
Dortmund's progress to the final has seen them win a tough group which included Real Madrid and Manchester City, before knocking the Spanish side out over two legs at the semi-final stage.
Bayern won the Bundesliga with weeks to spare, with Dortmund eventually 25 points adrift in second place, and Ribery feels European glory will be Bayern's if they play to their potential.
"I was impressed with how Dortmund managed to dismantle Real Madrid in the semi-finals, but we are only thinking of ourselves. We are stronger," the Frenchman declared.
"If we're all ready and willing to give 100 per cent we'll emerge victorious. We know Dortmund inside-out.
"It will be crucial not to put too much pressure on ourselves.
"I don't know whether we'll make it to the Champions League final ever again, which is why we want to give it everything we've got to finally hold the trophy."
Ribery's team-mate Mario Mandzukic says that playing at Wembley will fulfil a lifelong dream.
The Croatian joined the Bavarian giants in summer 2012 and is eager to play in a Champions League final at the first time of asking.
"I can hardly wait for the kick-off. Since I hit my first ball, I always dreamed of playing a Champions League final - and I also dreamed it would be at Wembley," said the 27-year-old.
"Now my wish is coming true. I hope this is football's reward for me giving my best to it, with fair play and hard work.
"I think Bayern's greatest strength is their team spirit. I have played for a lot of teams but I have never experienced anything like it."
