After market brake system
We have a 2001 38' HR Imperial with an engine brake but not an exhaust brake. Has anyone had a brake assist system installed? If so, what kind and are you satisfied with the result?

Agree on C which will have exhaust brake.
The L was offered with EITHER exhaust (less expensive) or engine compression brake (preferred).
Yes the 400 HP ISL engine was equipped with a Jake two stage brake. I do not ever remember seeing any 400 HP ISL engines with an exhaust brake. I know that Travel Supreme MH's with the ISL engine all had Jake Brakes std.
But the poster said his unit is a 350 HP ISC therefore I believe he has an Exhaust brake, as Cummins never built a ISC with a Jake brake from my research.
If he found the serial # on his engine and called Cummins they could advise what the engine was built with.
