The BORLA® exhaust note has become the quintessential soundtrack of high-performance motoring. And like all good automotive designs there is function behind the form. As any driving enthusiast knows, the sound of an exhaust provides more than just ear candy. It’s a communications conduit between car and driver. A link between human and machine. Borla Cat-Back and Rear Section 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 enthusiasts everywhere. Best of all Borla stands behind every system with a Million-Mile Warranty.

Replace the small muffler behind the primary muffler in the BORLA? “S-Type” system with Polyphonic Harmonizer 60680 to attain the “ATAK?” sound level (louder than “S-Type”). BORLA?’S Polyphonic Harmonizer Technology utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound to the BORLA? mufflers. The mufflers then enhance this sound to the character and volume appropriate for our Touring, S-Type and ATAK? systems. Built from premium T-304 stainless steel, superior to T-400 series (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA? stands behind every Polyphonic Harmonizer with a Million-Mile Warranty. Just what you’d expect from the world’s most experienced (and most winning) exhaust brand.
