Customer Reviews
Good Ram deletes, shipping slow
I ordered a Ram Cummins DPF delete kit and an EZ LYNK tuner. The parts arrived well-packed and fit my truck perfectly. Installation went smoothly, and the performance boost is noticeable. Shipping took almost two weeks, which felt a bit long, especially for an in-stock item. Overall, good value for the price though.
Flo Pro exhaust worked out
Got a Flo Pro exhaust for my Ford Powerstroke the other week. Was a little nervous about ordering online but it showed up pretty fast, like 5 days. Had my buddy help me put it on. It sounds real good, not too loud but you know it's there. My only gripe is the tracking info wasn't super detailed, but it arrived so no biggie.

Hey guys, thinking about grabbing a DPF delete kit for my Ram. How long does shipping usually take to like, Ohio or something? Need it kinda quick.
Are the delete kits on Diesel Dudes legit? Like, I've heard some horror stories about fake parts from other sites. Just wanna make sure.
