Just had a chat that flipped my view on those aftermarket EGR delete kits

I was talking to a senior tech at the Freightliner dealership in Springfield, and he pointed out something I never considered. He said, 'Skyler, those kits might get you a quick power bump, but they're murder on the downstream components when you skip the proper tuning.' He showed me a 2020 Cascadia with a cooked DPF that the owner swore was fine after a delete. Anyone else seen this kind of cascade failure firsthand?

My own delete kit adventure ended with a turbo that sounded like a bag of rocks. That "quick fix" cost me way more than just a tune. Learned that lesson the hard way.

Yeah, it's not just the DPF either. That extra heat and pressure works its way through the whole exhaust and can crack manifolds. You're basically trading one problem for a bunch of new, worse ones.

My buddy Carl out in Boise got a delete kit for his Ram last year. He was bragging about the mileage for maybe two months. Then his whole exhaust system, from the turbo back, basically fell apart. The shop said running that hot without the right computer changes melted stuff he didn't even know could melt. He ended up selling the truck for parts.
