MBRP Diesel Resonators (Aluminized & Stainless Steel)

I install this resonator on a 2006 Ram with 5.9 diesel to cut down on the drone inside the cab. The resonator is good quality and easy to install. I was getting an overwhelming drone in the cab while towing the camper or the stock trailer. The resonator did cut down the drone by about 40 to 50 percent, but not as much as I was hoping for. The exhaust is much quieter as well. Too quiet for me, but my wife likes it and is more enjoyable on long drives. The exhaust still has a nice deep rumble to it. I did not notice a loss in hp or torque, but my exhaust temp did slightly go up while towing.

Cut the in noise level about in half compared to 4" turbo back with the performance MBRP muffler. Much better for long trips. It is a straight through design, just a glasspack with bigger baffling.

My wife noticed a difference right away and was very happy about it. I run a Diamond Eye, quiet flow has a resonator in the down pipe with muffler it is a 4 inch system on a 2005 Dodge Cummins. This part added in the system brought the cab drone down even more. When towing around town at about 1500 rpm the drone was heavy. We also have a 2007 Cummins with the same Diamond Eye system and it is much quieter than the 2005. Installed this part on the 2005 and now around town we are able to have a conversation.

Had 4 inch straight pipe from turbo on my 2012 ram dieseland drone in cab was ridiculous. I installed this at the end of the Dow pipe and the drone is gone. Exhaust still sounds throaty. Recommend this resonator.

It took the drone out of my exhaust. Sounds great.

I have a 2007 F-250 crew cab FX4 Lariat and I have 4" MBRP turbo back 4"inch exhaust with a 7"inch tip. Its loud outside and can hear the turbo and everything else clearly. While doing 70-75 on high way driving it has a in cab drone noise that drives me nuts. with this Resonator installed it took the drone away almost 100%. If your paying a attention to the exhaust note you can still hear turbo it but its muffled and don't have to turn the radio up when driving any more. I can actually here my S&B intake when taking off again. I would definitely recommend it when your planing on long trip and or towing!
