Lawson D'Ath capped his Cheltenham debut with a fine goal as in-form Town comfortably saw off the challenge of out-of-sorts Exeter 3-0 at the Abbey Business Stadium.
D'Ath's fine exchange of passes with Darryl Duffy and subsequent clinical finish put Cheltenham ahead in the 55th minute after a goalless but entertaining first half.
And it was left for a brace from full-back Keith Lowe to wrap up victory, with third-placed Town having tasted just one defeat in their last nine while the Grecians suffered a fourth defeat in five winless matches.
Alan Bennett was denied by Artur Krysiak in the third minute after meeting a corner from former Exeter man Billy Jones. At the other end Scott Brown turned over a shot from Jimmy Keohane and blocked well from Steve Tully as Exeter grew into the game.
Jones cleared a Jamie Cureton effort off the line and Brown beat away Liam Sercombe's drive, but Cheltenham ran away with it after the break.
After D'Ath's opener Brown did well to block a swerving drive from Cureton before Lowe made it two-nil.
The right-back reached Steve Elliott's flick-on from Jones' corner to force the ball over the line from close range.
And Lowe made sure of the points with a second tap-in after Elliott nodded down another Jones corner in the 87nd minute while substitute Jeff Goulding saw a late effort hit a post.
