Those of you wishing to upgrade to a 4 or 5 inch exhaust and would like to use an exhaust brake..... PacBrake builds both sizes... They can be calibrated to the correct back pressure for the HO Cummins... . They are used on Cummins, Cat, IH in mid range engines... . Contact your local Pac Brake Distributor for more information... . We've sold several for for second generation trucks who have put larger turbo's on their engines... .
We've delivered our first pallet of exhaust brakes to our customers on our list..... I'm down to one or two... and waiting a new shipment next week... .
Have a great evening.....
Jim
