Donaldson Exhaust systems are original equipment on most pre-2007 medium- and heavy-duty trucks manufactured in North America. Donaldson engineers work with many OE truck and off-road equipment manufacturers to design and build quality exhaust systems to meet specific performance requirements.
Got the Donaldson resonator to replace an old one. It does its job, and the sound is better, but the packaging came a bit dented. Not a huge deal for me, but just a heads up!

Easy installation, solid product
The Donaldson M090072 resonator was a breeze to install. I’m not super handy, but I got it done in under an hour. The sound quality has improved—definitely a solid upgrade for my ride!

Not what I expected
I ordered the Donaldson resonator thinking it would give my car a significant boost in sound. It's nice, but honestly, I thought it would be louder. Seems fine overall, but I’m a bit underwhelmed.

Came damaged, but works fine
Unfortunately, the resonator arrived with a small dent, which was disappointing. However, I installed it anyway, and it functions just as it should. Just wish the shipping had been better!

A must-have for my setup!
I’ve been using the Donaldson resonator for a few weeks now, and it has made a noticeable difference. The sound is fantastic, and I love the build quality. Definitely a great addition for anyone looking to enhance their exhaust!
