really. i had no clue that changing the injection events would make it that much more quite... well i guess i just will have to learn to live with a quite diesel...

 

There is nothing more pleasing to my ears than my loud obnoxious Cummins!

 

I consider my 06 pretty loud. Maybe it's because I've never driven a diesel before this one. I usually do have to turn it off at the drivethru!

 

pull up next to and older power stroke and you will hear the differance right away... hell an older diesel for that matter not just the power stroke.

 

First, I am in no way shape or form associated with ATP or their president Tim Thompson, just a very satisfied customer. I purchased the valve cover and oil pan blankets for my 06 Megacab to make my ride quieter. I visited ATP factory in Irvine CA on my way to May Madness 08 for the install. Two of his technicians did the install.

In addition to the valve cover and oil pan blankets, Tim had his technicians install an exhaust manifold, turbo/down pipe heat shield. The heat shield is made out of a high tech fiber sandwiched between Inconel alloy skins. Let me tell you this heat shield works! When I arrive at Pahrump Nugget’s parking lot for May Madness from Irvine, while the engine was still running, I popped the hood and touched the top of the manifold heat shield expecting to get my fingers burned. To my surprise, it was not hot. It was no hotter than the ambient air around the engine bay. This tells me that the heat from the engine is kept within the manifold, turbo (thus creating more heat energy) and out the tailpipe and not heating up my engine bay and the delicate ECM and other electronics and wires.

Wit all these engine sound suppressions it is making a difference. Although you still could hear the Cummins making power, it is now much quieter.

Tim’s operation is top notch. His main business is industrial, marine and military. Since he owns a CTD, he designed a kit for our truck. ATP’s product is not cheap. However, you will get the best there is from a company that’s been doing engine sound suppressions for over 35 years. Give him a call and tell him that a TDR member from Sacramento sent you and he will take care of you. ATP can be reached at (800) 826-8417, http://www.atpwrap.com/

In addition to the engine sound suppression, I’ve also addressed the noise coming from the entire cab (doors, back and floors) and hood. I’ve lined the interior and exterior doors with Dynamat Xtreme and Second Skin Luxury Liner Pro (acoustic blocker/filter). If you tap on the doors, they are dead and will not resonate. I’ve just finished lining the hood and will add Second Skin Motor Mat. You can see my doors with just the Dynamat Xtreme and then with Luxury Liner. If you look closely inside the speaker hole (next post pics), the door skin on the outside of the truck is linned with Dynamat Xtreme and then Over Kill Pro (sound filter). The hood is still not finished. IMO Dynamat Xtreme followed by Second Skin Damplifier Pro and followed by Raammat are the best sound deadner on the market.
