Customer Reviews
Good stuff, but shipping was slow!
Anyone else check out The Diesel Dudes? I got an up-pipe for my truck and the product itself is solid, really happy with the quality! It shipped to Canada no problem, which is awesome because sometimes it's hard to find places that do. My only gripe is that it took almost two weeks to get here after it shipped, which felt a little long. Still, the parts are great!
Super happy with my new exhaust!
Got a Flo Pro exhaust for my GM Duramax and I absolutely love it! The sound is incredible and the fitment was perfect. It arrived a day earlier than expected too, which was a nice surprise. Seriously impressed with how quickly it shipped and the quality of the product. My truck feels like a beast now! Definitely recommending The Diesel Dudes to all my buddies. I'll be back for a tuner next, for sure!
Good quality, consistent service
I've ordered from The Diesel Dudes a few times now, and they're always reliable. This time I got an EGR delete kit for my Ram. It shipped out fast, just like my last exhaust system did. The parts are always well-packed and the quality is there. That consistency is why I keep coming back.
Smooth order, good support
I bought a Ford Powerstroke DPF delete kit and an SCT tuner. The website was easy to navigate, and finding the right parts for my truck was simple. Shipping took about five business days, which was exactly what they said it would be. One of the sensor plugs seemed a bit off, so I called customer support. They were helpful and quickly sent out a replacement without any hassle. The kit itself was high quality, and the installation went smoothly with no surprises. It's good to know they back their products.

Looking at their full delete kits, do I absolutely need to get a tuner with it? Or can I just install the DPF delete and be good to go?
Hey guys, thinking of grabbing a full delete kit for my '18 Ram from here. Anyone know how long shipping usually takes to like, Texas? Need it before a road trip.
Is The Diesel Dudes actually legit? Seen some sketchy sites selling similar stuff. Just wanna make sure I'm not getting ripped off.
Hey, I'm trying to decide between a Flo Pro exhaust from here or going with an MBRP from XDP. Any experience with the Flo Pro stuff from The Diesel Dudes?
Does anyone know if The Diesel Dudes does any kind of discount for military? Thinking of getting a full bundle and every bit helps.
