Turbo back MBRP (any droan or interior noises)

[barriesr/t]

Hey all,

looking at adding a turbo back muffler only system to my 05 6.0. I'm all game but worried about interior noises, 1st being droan.

I've listened to all the you tube clips but can't seem to get a real feel for it.

cab drone is minimal with a muffler installed.

I've got a 4'' turbo back MBRP, muffler but no cat on my '06. The drone is really minimal. Honestly you don't even notice it under normal driving conditions.

When I installed my old 4" I didn't align the downpipe perfect so at 1500 rpms there would be a very annoying droan in the cab but I made sure when I installed my 5" that I got everything perfect and now all I hear is whistle from the turbo.

Yeah, I have a performance muffler on mine and even with it you still can't hear any droan unless you hammer down, but even at that, it's still not as loud as a straight pipe.

I have a 4" MBRP turbo back system. I don't have any drone but right after I installed it I have a wierd and very annoying noise between 1500 and 1700 RPMs. After looking under my truck I noticed that the hanger for my cat delete pipe was rubbing against my frame. Cut off about an inch of the hanger and the noise is gone!
