Construction & Design

The ARMOR PLUS exhaust system is crafted from T409 stainless steel, chosen for its excellent corrosion resistance and value. This alloy protects against rust and corrosion, making it ideal for a variety of driving conditions except extreme winter environments with heavy salt exposure. All tubing is mandrel bent, providing smooth bends without ripples or restrictions, which maximizes exhaust flow and contributes to improved engine breathing and overall performance.

The single side turn down exit not only gives the Jeep a distinctive, rugged look but also efficiently directs exhaust gases away during off-road driving. The system’s robust construction ensures it can withstand the toughest road and trail conditions, making it a dependable upgrade for Jeep Wrangler owners.

Performance & Sound

This exhaust system enhances your Jeep Wrangler’s performance by increasing horsepower and torque through improved exhaust scavenging. The mandrel-bent design reduces backpressure, allowing the engine to breathe more freely and operate more efficiently. Additionally, the ARMOR PLUS system produces a rich, mellow exhaust note that is aggressive yet refined, perfectly complementing the Jeep’s rugged character without being overly loud.
