PAC BRAKE'S NEW PRXB EXHAUST BRAKE
LEAH DRAPER:
Am planning to have Henderson's Line Up in Oregon add/change my PacBrake to the New PRXB brake that will give greater braking than the installed exhaust brake on the Cat C-9 (425 hp). Does/has anyone any experience with this this new Brake? Would really appreciate some feedback ya'all.
Have 2008 Beaver Contessa, towing a PT Cruiser.

I installed the PRXB myself in a half an hour. Two clamps and one air line for the ram. I purchaced it direct from Pac Brake in March 2008 for $800 + freight. We now have 15,000 on the brake. The only difference is lower rpm braking. I'm happy with it.
We have a 2005 Montery 36' w/4 slides c9 400hp 32,800lb. Towing 2006 Saturn Vue 4,200lb.
Gerald Farris:
There are two types of exhaust brakes used on the 2008 C9 Contessa. If your coach has a diesel particulate filter with a variable geometry turbocharger and a regenerator, the PRXB exhaust brake is not normally recommended.
The other type uses a conventional exhaust brake (Pacbrake). If this is what you have, it is very simple to install the new design Pacbrake.
I know of one Contessa owner that has had this done, and he said that even though the braking was improved, especially at lower RPM's, that it was not the major improvement that was advertised. If you keep the RPM's up (as per operating instructions) when using the Pacbrake, you will probably not notice the difference.

We looked into it about a year ago and aftr talking to several diesel mechanics and RV net etc decided the pain ($$) out weighed the gain in preformance which is only at lower RPM mentioned above.
LEAH DRAPER:
Gerald, Why would the brake in the case you describe below, not be recommended? Can you be more specific, I certainly would not want to damage the engine or invalidate any warranty.
