Jacobs Exhaust Brake for Cummins http://www.jakebrake.com/products/ld-exhaust.php I have been thinking about getting one but wanted you guys to let me know what you think. Anyone have one
what do to they sound like
Do they sound like the big rigs do or not.
Also are they hard on the motor at all i have heard that they are not good for the motor. Any input please. thanks

 

I wouldn't think it could be hard on the motor espically since cummins is backing it! I wish I could get one for my truck
