The Banks Power Monster Exhaust System (SKU 51315-B) is a cat-back performance exhaust engineered for 2004-2006 Jeep Wrangler TJ and LJ Unlimited models equipped with the 4.0L inline-six engine. Built entirely from heavy-gauge stainless steel, this system replaces the restrictive factory exhaust with a straight-through design that dramatically improves airflow while delivering a bold, authoritative exhaust note.
Key Specifications:
- Construction: Mandrel-bent stainless steel throughout
- Tailpipe: Supersized 2.5-inch diameter
- Tip Finish: Cerakote black tailpipe tip
- Style: Cat-back, single exit
- Flow Rating: 501.2 CFM at 1 psi (140% improvement over stock)
- Dimensions: 31" L x 20" W x 8" H, 25 lbs
- Includes: Stainless Monster muffler, stainless 2.5-inch tailpipe, black tailpipe tip, and mounting hardware
Independent flow testing shows the Banks Monster muffler outperforms the factory exhaust by 140 percent and beats the nearest competitor by roughly 44 percent. This reduction in backpressure lowers exhaust gas temperatures and unlocks additional power and efficiency from the catalytic converter back. For maximum performance gains, Banks recommends pairing this system with the Banks TorqueTube header system.
Manufactured in the USA, this system is designed as a direct-fit solution for TJ and LJ Wrangler owners looking for a durable, high-flow exhaust upgrade backed by real-world dyno and flow-bench data.
