I have been looking a jake brake for the 5.9 but all i find is exaust breaks and i dont want one i want my truck to sound like a semi

 

Not gonna happen.

 

why i would think some one out there has made the head mods for it

 

you cannot match the sound of a semi.

 

oh yea i know that thats not what i am after i want the breaking part more but at the same time it would be cool as hell havin the sound

 

I believe Pac brake is developing an engine brake for the 5.9L's but I cant imagine it's gonna be cheap. Exhaust brakes run about $1000.00 so a complete engine brake kit might be around $5000.00

 

Thats crazy sane but that would bee pretty pimp to have an actual engine brake that would be awsome i just dont like the possible price. What would all be involved in and engine brake for the 5.9s like what would you have to add or chang over

 

thankyou

This is the installation procedure on a 3406 Cat but it would be similar on a 5.9 Cummins.

That'd be cool for a cummins but man I dont know if $5k cool unless you had a loaded trailer on constantly but thats just me.
