What brand of exhaust brake you you Guy's recomend for an 05' Cummings?

 

on my 99, i got the OE one by Jacobs. it's turbo mounted and you can't really tell it's there.

 

how much did the jacobs cost u

 

I have a auto, won't I need a controller? Thanks

 

I'm getting a Pacbrake for the '07 one of these days. Starting in either '05 or '06 the ECM is programmed to integrate the 48RE torque converter lockup with an exhaust brake - pretty much plug and play. I like the Pac because it's air operated as opposed to the OEM vacuum Jake. The Jacobs requires an engine mounted belt-driven vacuum pump. Pac uses an electric air compressor/system or any onboard air system of your choice which can also be used for other things depending on how big of a tank you install.

 

it's minor, but it's gear driven.
i picked up my jake second hand for $400.

 

It's minor, but in the case of a commonrail that does not have a factory vacuum pump (the OP's truck for example!) according to the installation manual it's belt driven:

Actually, I view it as kinda "major" because there's been alot of problems reported with the new jake pumps.

 

oh, i see. i only work on my truck, so...
that's one long installation manual. mine was short and sweet, unbolt elbow, put in brake, run the harness.
third gens don't have a vacuum pump from the factory?

 

Nope.

 

The 3rd gens don't have an OEM vacuum pump because the brakes are now 'hydro' boost!
DC didn't release the software for an OEM exhaust brake on an auto until the '06 model year. I know because I had an '05 and they never did release or authorize it for the exhaust brake. A lot of us were mad at them for never getting that done.
The install on a 3rd gen really doesn't involve much more than what you stated. It does tap into the ECM so the computer knows when it is on and can lock the converter appropriately.
I haven't heard a lot of people talk about it locking up in 2nd! If you have the brake on, place the 'PRNDL' selector in 2 and the torque converter will lock at 27 MPH and above. I was using this for take off with our heavy toy hauler in the big cities and it really helped. I could also force a down shift to 2nd and let the exhaust brake come on for added engine braking on steeper hills. This helped quite a bit since towing that heavy, using 3rd to engine brake below about 35 doesn't do a whole lot.
I run the exhaust brake almost all the time. On a normal take off it causes the torque converter to lock up in 3rd at 30 mph. On an easy take off like that this helps a lot by doing away with slip in the converter. I'm also sure this will help brake pads to last a lot longer.

(What has been happening with the OEM vacuum pumps? I wouldn't mind it not 'braking' since I really like my exhaust brake!)
