    Donaldson diesel mufflers are very popular.

    I went with a 17” FTE resonator to tone it down a bit.

    There are quite a few great mufflers out there for sure. We sell alot of the twister mufflers from flo pro. Most people put them right after the downpipe to keep the cab drone out.

    Just put in my 17" FTE resonator last night, so much better, yet still sounds like it should. I just have a stock 4" with the delete pipes, and put the resonator right after the downpipe.
