If you are looking for a DPF back exhaust upgrade for your 2020+ Chevrolet Silverado 2500 HD that matches the size and presence of your truck, then this is the system for you. 

🚗 Suitable for:

📦 What’s included:

• 1 x Manta Performance Stainless Steel 4in to 5in Turbo back system, with cat & without muffler, ‘loud’ system. (Available in quiet, medium or loud). 

🛠️ Fitment Details:

• For 2024–2025 Silverado HD, both Turbo-Back and DPF-Back systems typically require a tune due to added sensors and calibration differences.
• The 2024–2025 DPF-Back fitment may require an OEM tailpipe trim (100mm from last weld) to mate with the Manta system.
• We recommend your consult your ECU tuner before installing.

⚙️ Why Choose This:

• 10 Year Warranty on Manta Stainless Steel Exhaust Systems
• Built in Australia to suit your American truck 
• A high-flow exhaust reduces back pressure and improves turbo response on the 6.6L DuraMax. Manta’s 4″ Turbo-Back and DPF-Back systems with 5” tailpipe, are engineered for stronger exhaust flow and a deeper tone. Options with and without mufflers let you decide between quiet daily driving or a loud and proud V8 note. Turbo-Back installs for some model years require ECU tuning to optimise performance and avoid drivability issues.
