I have a 5. 9 cummins in a 06 ram 2500 and I use to have the jake brake installed when I had the stock turbo but then I upgraded the turbo to a HTB2 64/13 from High Tech Turbos and the jake brake would not fit. It hits the firewall. And also the air pump the opens and closes the valve on the brake is in the way for the 1/2 inch vulcan big line kit to go into the CP3 injection pump. My question is if anyone knows a exhaust brake the will fit with the turbo that I have now? An exhaust brake that dosent interfere with anything else already on the truck? Thanks.
