Many companies for a lot of years offered DPF-delete kits, and many still do. You just won't find them (or their required PCM tuning) here at Stage 3. Both the EPA and California Air Resource Board (CARB) have come down hard on both manufacturers and retailers of those DPF-delete kits and the PCM tuners that could program for them, and we frankly don't need the heat, or think the performance gains are worth the problems. In any case, we carry standard DPF-back kits, tuning, and other bolt-on upgrades that won't get you into hot water but will get your 6.7L Super Duty running stronger than you could ever want or need.
Here at Stage 3 Motorsports, we're always striving to find the best aftermarket components to improve the power, handling and exterior appearance of not only your Super Duty, but our project trucks as well. We just threw one of MBRP's 4" Installer-Series DPF-Back Exhaust Kits on our new "Project Ice Box" 2014 F250 6.7L Lariat Crew Cab Project Build and were very impressed right out of the gates. With its enormously large tubing and even larger matte black tip, this bad boy gives you all you could want in a high-performance exhaust kit and more. Not only do you get an awesome look with the menacing black tip that exits behind the rear passenger tire, but the sound gives that perfect low rumble at idle and then a throaty roar when you rev the engine -- all the sound you could ever ask for to match the aggressive ruggedness of your Super Duty.
