Just thought I would share what I did to my exhaust for someone who might be in the same boat as I was..
I had just a delete pipe on my truck and for my taste it was too loud at idle, while putzing around town and I had a drone at around 40-50.
I know a lot of people might think the delete pipe only isn't that different than stock, but my experience was it was noticeably & annoyingly louder than stock.
A member here, Drunk on Diesel, suggested I install a Donaldson muffler (Muffler 4" In 4" Out, M085171, Donaldson - Ryder Fleet Products
) and thank him later.
Well it's later and thank you!!
The truck is SO quiet at idle, there is absolutely no drone at all and its quiet just driving around. It's stock quiet in my opinion - I can hear myself think. It still sounds awesome when I get on it and you can still hear the turbo.
