JBA 409SS Single Rear Exit Cat-Back Exhaust for 2003-2006 Hummer H2 (6.0L) 40-3023
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2003-2006 Hummer H2 Base (6.0L).
The JBA Single Rear Exit Cat-Back Exhaust system is engineered to replace the restrictive factory piping on your Hummer H2 with free-flowing, mandrel-bent 409 stainless steel tubing. This system is specifically tuned to provide a significant increase in exhaust efficiency and a more aggressive tone without becoming overwhelming inside the cabin during highway cruising.
Built for long-term durability and ease of installation, this kit features heavy-duty 409SS construction and includes high-quality hardware with factory-style hangers for a precise fit. The system is completed with a polished chrome stainless steel tip, providing a high-end finish to the rear exit.
- Large diameter 409 stainless steel mandrel-bent tubing for maximum flow
- High-flow stainless steel performance muffler reduces backpressure
- Polished chrome stainless steel exhaust tip
- Factory-style hangers and high-quality hardware included for secure mounting
- Manufacturer Part Number: 40-3023
