REDBACK Extreme Duty 4" Muffler Delete Solution for your Vehicle Universal Application
The REDBACK Extreme Duty 4" Muffler Delete Pipe (XP00273-40) is the ultimate performance upgrade for high-output off-road builds seeking maximum exhaust volume and unrestricted flow. Designed as a modular replacement component for Redback Extreme Duty 4-inch systems, this pipe removes the muffler entirely to deliver an aggressive, raw engine note. Built with heavy-duty 409 Stainless Steel and thick 10mm flange plates, it is engineered to survive the most demanding Australian conditions while maintaining a perfect fit through its specialized offset/offset configuration.
Key Features:
- Australian Designed and Made β Engineered specifically for the harsh vibrations and extreme environments of heavy-duty 4x4 touring.
- Maximum Exhaust Volume β Classified as a "Loud" pipe-only option, providing a raw performance sound by removing all internal dampening.
- Unrestricted Flow β Straight-through 4" (101mm) design eliminates backpressure to optimize turbo spool and significantly lower exhaust gas temperatures (EGTs).
- 409 Stainless Steel Construction β High-grade stainless tubing offers excellent thermal stability and long-term durability against the elements.
- Extreme Duty Flange Plates β Heavy-duty 10mm thick, 4-bolt plates ensure a rigid, leak-free, and warp-proof connection under high stress.
- Offset / Offset Configuration β Precision-aligned for clearance and seamless integration with specific Redback Extreme Duty 4" system geometry.
- Premium Heat-Proof Coating β Finished with high-temperature paint for added protection and a stealthy, professional underbody appearance.
- 10-Year Warranty β Backed by Redbackβs industry-leading warranty for ultimate peace of mind on and off the tracks.
