Borla S-Type Cat-Back Exhaust System | Chevrolet Silverado 1500 ZR2

Pipe Diameter: 3.5" Split Into 2.75" Tail Pipes

Tip Exit: Single Split Rear Exit

 

This BORLA® Cat-Back™ system was designed specifically for the 6.2L Silverado 1500 ZR2 and Sierra 1500 AT4X. The 3.5" diameter system has dual 2.75" turn down tail pipes and features the classic BORLA® S-Type sound level with no drone inside the vehicle. Replace the small muffler behind the primary muffler in the "S-Type" system with Polyphonic Harmonizer 60680 to attain the "ATAK®" sound level (louder than "S-Type"). Optional "True Dual" Cat-Back® system available, 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 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 flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.

Give your ZR2 or AT4X the sound it deserves, bolt on a BORLA®. 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.

BORLA® Cat-Back™ system

This commonly-used term was actually originated by Borla, who pioneered the concept. "Cat" is motorhead shorthand for "Catalytic Converter." A Borla Cat-Back™ exhaust replaces your entire stock system from the catalytic converters "back” to the tips exiting the bumper. This type of system delivers the most dramatic upgrade in sound, because it includes improvements to virtually all the undercar piping, incorporating Borla’s ultra-smooth mandrel bends, X-Pipe technologies, pipe diameter specs and other characteristics that shape the sound. Borla Cat-Back™ systems are available for a wide variety of popular cars and trucks, and are offered in your choice of sound technologies — ATAK®, S-Type and Touring — each with their own distinct volume and character.
