Description
The ROCK BASHER 3-Inch 409 Stainless Steel Cat-Back Exhaust System is engineered for off-road enthusiasts and performance-driven truck owners who demand durability, clearance, and aggressive sound. Designed specifically for rugged terrain, this system combines race-proven construction with a precision-engineered fit for reliable performance on and off the trail.
Constructed from 3-inch mandrel-bent 409 stainless steel tubing, this cat-back exhaust delivers improved exhaust flow while maintaining exceptional strength and corrosion resistance. The mandrel-bent design ensures smooth airflow throughout the system, helping unlock available horsepower and torque without compromising reliability.
At the core of the system is a high-flow 409 stainless steel muffler, tuned to produce a deep, powerful exhaust tone that enhances the driving experience without excessive drone. Whether crawling over rocks or cruising the highway, the sound profile delivers authority and performance.
The hi-tuck exhaust design provides increased ground clearance, making it ideal for extreme approach and departure angles. This design helps protect the exhaust system from damage when navigating rough terrain, steep climbs, or descents.
Installation is straightforward thanks to the use of factory-style flanges and hangers, allowing for a true bolt-on installation with no cutting or modifications required. An interlock flex pipe with an internal liner adds durability and reduces stress on the exhaust system during engine movement and off-road articulation.
Every system is 100% MIG-welded for superior strength and long-term durability. Utilizing advanced computer-aided design (CAD) technology, this exhaust system is engineered for precise vehicle fitment and consistent quality.
Manufactured in Corona, California, aFe POWER exhaust systems are built to meet the demands of performance enthusiasts and off-road adventurers alike.
