Construction & Design

The Borla S-Type Climber exhaust system is crafted from T-304 stainless steel, known for its exceptional durability and resistance to rust and corrosion. This premium material ensures the system maintains its structural integrity and appearance even after years of exposure to harsh off-road environments. The exhaust features mandrel-bent tubing, which preserves the internal diameter throughout bends to maximize exhaust flow and reduce backpressure.

Its high-clearance design is tailored to the Jeep Wrangler JL’s off-road capabilities, allowing for better obstacle negotiation without compromising exhaust performance. The brushed stainless steel turn down tip not only adds a distinctive look but also directs exhaust gases downward and away from the vehicle, reducing the risk of damage during rock crawling.

Performance & Sound

The Borla S-Type Climber system enhances your Jeep Wrangler’s performance by improving exhaust scavenging and reducing restrictions. This results in a more responsive throttle and potential gains in horsepower and torque. The signature S-Type sound is aggressive yet refined, providing a deep, throaty exhaust note that is unmistakable without causing unpleasant drone inside the cabin, making it suitable for both spirited driving and daily use.
