Manta Performance Exhaust for Chevrolet Silverado 2500 (2020–2025) — Big Flow, Big Sound for a Big Rig!
The Manta Performance Exhaust for the Chevy 2500 HD 6.6L Duramax delivers a louder, cleaner flow and that signature Manta V8 tone. Choose between Turbo-Back or DPF-Back configurations to match your goals for power, sound, and emissions compatibility. Stainless steel systems come with long-term durability; aluminised options give a more affordable alternative.
Why upgrade your Silverado 2500?:
A high-flow exhaust reduces backpressure 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.
Fitment & tuning notes:
2020–2025 Silverado HD with DPF-Back Manta systems installs plug-and-play in most configs. Turbo-Back options for 2020–2023 will require a tune after installation. 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 — consult your ECU tuner before installing.
Materials, warranty and options:
Stainless steel systems are designed for a long service life and heavy use. They can handle anything you throw at it, while backed with a 10 Year Warranty Aluminised steel provides a lower upfront cost while still maintaining Manta fitment and quality, backed by a 2 Year Warranty.
Performance & sound variants:
Our Chev 2500 systems come in many different sound options to suit your needs. Decide between DPF-Back for emissions-friendly upgrades and Turbo-Back for maximum flow. Quiet (muffler) and loud (no muffler, straight through). Choose the Quiet option for towing and for long trips; and Loud for that full V8 sound that turns heads. Expect a deeper idle, stronger midrange and crisper turbo spool.
Installation & dealer support:
We recommend professional fitting at an authorised Manta Dealer for warranty compliance and peace of mind.
