Whats the quietest 5" muffler?

[Blacksdieselhp]

I currently am running a 5" magnaflow exhaust system. I really like it except for the normal 2000 rpm drone that most of these systems have. I want to leave the 5" pipe and just replace the muffler with something else. I have used the Donaldson muffler and liked it ok. What have you guys tried that doesn't have the drone at 2k rpms?

as far as something that isn't going to hurt performance, I think the M090535 donaldson is about the best thing going (pretty sure that's the right PN... off the top of my head)

Yeah, a 5-inch Nelson/Fleetright/Donaldson will probably be the best...

You can look at the different configurations on their websites... they make a bunch of different lengths and CFM ratings...

I have mbrp 5 inch exhaust from the turbo back, and it is pretty quiet and no drone.



However my exhaust has been a lot quieter once the twins went in
