Steve L Posted February 14, 2022 Share Posted February 14, 2022 I have a 454 Quantum with a jake brake and it also has an exhaust brake, I also have a CH 400 jake brake engine with no exhaust brake, also seen a CH E7 with exhaust brake. Why were the exhaust brakes fitted to some E7 engines, was it noise suppression or did it add to braking efficiency. If it helps braking could I fit exhaust brakes my CH and 2 R model 350 E6s. The 350s both have dynatards. Quote Link to comment Share on other sites More sharing options...
