Transform your Toyota Tundra with the Borla 140638 Touring Cat-Back Exhaust System, designed for 2014-2021 models equipped with 4.6L or 5.7L V8 engines, automatic transmission, 2WD or 4WD, and specific wheelbases of 145.7 inches across Regular Cab Long Bed, Extended Cab Standard Bed, and CrewMax Short Bed configurations.

Crafted from premium T-304 stainless steel, it outflows the factory exhaust while weighing less for improved performance.
Key Features

- Straight-Through Muffler with Internal H-Pipe: Patented multi-core technology and H-pipe balance sound and performance, providing a refined V8 growl without interior drone on highway drives.
- True Dual Split Rear Exit Design: Full cat-back layout from catalytic converter back with 4-inch polished T-304 stainless steel tips adds aggressive motorsport styling and even exhaust distribution.
- Precision CNC Manufacturing: Computer-controlled fabrication guarantees perfect fitment using factory mounting points for straightforward installation and reliable long-term performance.
Product Notes
- System weighs approximately 39 lbs, lighter than the factory exhaust for better handling and acceleration.

- Ships in one heavy-duty box with protective packaging; dimensions 52" L x 20" W x 20" H.
