Description

Transform your 2015.5–2016 GMC Sierra 2500/3500 HD or Chevy Silverado 2500/3500 HD with the 6.6L Duramax LML engine using the TruckTok 5-Inch Downpipe-Back DPF/EGR/DEF/CCV Delete Kit with Mini Maxx V2 tuner . This kit is built with T-409 stainless steel and features a massive 5-inch turbo-back exhaust system for maximum airflow and aggressive sound. By removing restrictive emissions components like the DPF, EGR, DEF, and CCV systems , you’ll reduce backpressure, lower EGTs, and prevent costly engine failures — all while unlocking more horsepower, torque, and fuel efficiency. The included Mini Maxx V2 Delete Tuner is a game-changing race tuner that handles everything from recalibrating your speedometer to clearing DTC codes and providing real-time digital monitoring of over 20 engine parameters. Quick to install and simple to use, it’s the ultimate all-in-one diesel tuning solution. To further protect your engine, the kit’s CCV vent system reduces oil deposits inside your intake, keeping your Duramax cleaner and extending engine life. A muffler option is available if you want a quieter, more refined exhaust note without sacrificing flow or power. ⚙️ Kit Includes: Mini Maxx V2 Delete Tuner 5″ DPF pipe kit (downpipe-back) Air intake closing plate Exhaust block-off plate Three-terminal cooling hose Clamps & hardware (OE-style hangers included) ✨ Key Features & Benefits: Race-proven performance – 5″ turbo-back design maximizes airflow Lower EGTs – reduce stress on your Duramax under load More power & torque – unleash hidden performance potential Fuel savings – many owners report up to +5 MPG gains Cleaner engine – CCV vent system reduces oil buildup in intake/intercooler Tuner advantage – Mini Maxx V2 delivers smoke-free, efficient race tuning
