BORLA® Cat-Back™ and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed 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 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-controlled CNC manufacturing ensures an accurate fit.
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.
Warranty Valve Note: BORLA only warranties moving parts, such as valves and actuators for one year. This system includes functioning active exhaust valves, similar to those in the stock exhaust, and is recommended for most customers. Active exhaust valves in this system will improve sound quality.
Warranty Valve Simulator Note: BORLA only warranties moving parts, such as valves and actuators for one year. This system includes active exhaust valve simulators and is recommended for cars with significant modifications. The active exhaust valves in the stock exhaust have been removed, valve simulator mounts on the outside of the pipe allow the stock valve motors to be re-attached to prevent an error code.
Warranty Finish Note: BORLA exhaust systems are covered under our Million-Mile warranty with the following exceptions. Borla will warranty black coatings, tip finishes, and carbon fiber parts for one year.
