The Saints head to Sandy Park just six days after the crossbar heartbreak of Milton Keynes, and the flanker says that the agonizing loss to Saracens will be a big motivation this weekend.
"We were frustrated but there were a lot of positives from the Saracens game and we'll be looking to make amends on Saturday," he said in today's media session.
"Exeter have a great record at home, and we're aware how tough it is to play there. But we've won there in the past and need to make sure we're in the winning mindset on Saturday."
The Saints are two points off the play-off places as the Aviva Premiership Rugby season enters its second half. But with 10 matches still to play Dowson says that there is more than enough time for the team to build momentum over the coming weeks and months.
"There are going to be periods in the season where you're winning and periods when you're not," he added. "The bounce of the ball goes your way or it hits the crossbar, and when those things happen you have to stick together.
"You don't have to be top of the table during the year to win the league. All you can control is what you do and how you play.
"The league is more competitive and there are more teams who are in the mix than in the past couple of years. So what we need to do is keep evolving and keep playing well, and stay concerned about what we're doing."
