Borla cat-back exhaust system.
Part number: 140647
This system INCLUDES MDS (multi-displacement system) valve simulators which ELIMINATE the MDS valves. This avoids any warning lights on the dash while providing maximum flow at all times. The system delivers the classic S-Type sound with no drone inside the vehicle. Tips NOT included. Use factory valance / tips. 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. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
A cat-back system replaces everything behind the catalytic converter and leaves emissions equipment in place.
