I have the borla ATAK with the carbon tips. It's loud, overly loud, frankly. I didn't install it, guy I bought it from did. It's pretty aggressive when you really hammer it. I have the whipple intake, seems great. Lots of discussion about using a tuner as it leave a footprint. I have the RaceChip in mine which plugs into 4-5 connectors and gives great gains. Again, came with the truck, but works well and posts similar power numbers. I'm a big fan of the guys at Burger Tuning, they tuned up my BMW M's and are a really smart shop. The JB4 for the Eco is a great tune and not too expensive. If I didn't have what I do, I'd do the JB4. https://burgertuning.com/collections/ford/products/2018-ford-f150-raptor-jb4
