Ocean Response,
Most of the inertia type brake controllers usally don't opearate unless they get a signal from the brake light switch. As long as the exhaust brake doesn't activitate the brake lights, there shouldn't be a problem.
I have been towing nearly 4 years with an exhaust brake and never had a problem with the exhaust brake activating the electric trailer brakes.
