Overview

The BORLA® R&D Team has developed an awesome sounding exhaust for your Kia K4. Our 2.25" diameter Axle-Back™ system is specifically tuned for the 2.0L engine. The S-Type system delivers a sound that is much sportier than stock, yet still refined and far from obnoxious. Not to mention, a drone-free driving experience for comfort during cruising speeds. The exhaust exits thru a 2.25" brushed T-304 stainless steel turn down spout with a laser cut BORLA® logo. BORLA® Cat-Back™ & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA® Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum a flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Bolt-on a BORLA® and get the sound to match your Kia's Performance. Each BORLA® Exhaust System is built from premium T-304 austenitic stainless steel to give you the absolute best in performance and durability. Best of all, BORLA® stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
