Alan Gow's strike in the last 10 minutes denied Wycombe three points and ended Exeter's four-game losing run in League Two.
Wycombe led when Josh Scowen's drive deflected off Steven Craig's chest and wrong-footed keeper Artur Krysiak.
Scowen was fortunate to only receive a yellow card for a lunge on Liam Sercombe after the break.
Gary Doherty's header was cleared off the line before the Grecians responded with Gow's well-taken leveller.

Wycombe manager Gareth Ainsworth told BBC Three Counties Radio:
"I thought first half there was only us in it.
"We've stopped the losing run in the league which is good.
"I really believe we did play good football in the first half.
"The hardest thing for me now is picking the lads up because they're a bit down."
