Borla 140940 Cat-Back Exhaust System 2.5" True Dual ATAK Toyota Tundra 3.4L

The Borla 140940 Cat-Back Exhaust System delivers aggressive sound and enhanced performance for the Toyota Tundra 3.4L, including hybrid models. This premium system features a 2.5" diameter true dual design with two complete tail pipes—not just dual tips—providing authentic dual exhaust flow and sound.

Advanced Sound Technology:

Engineered with Borla's exclusive ATAK (Acoustically-Tuned Applied Kinetics) muffler and Polyphonic Harmonizer Technology, this system creates multiple exhaust notes that harmonize for a clean, rich, full-bodied sound without drone. The patented Polyphonic Harmonizer uses pipes of varying diameters and lengths inside the muffler assembly to deliver an aggressive tone that remains refined during highway cruising.

Performance Features:

• Merge X-Pipe design for increased horsepower and improved exhaust note
• Mandrel-bent tubing ensures maximum exhaust flow and power gains
• True dual outlet design with two independent tail pipes
• Dual 4.5" round bright chrome tips on T-304 stainless steel
• CNC manufacturing ensures precise fit and optimal performance

Construction and Fitment:

Built from premium austenitic T-304 stainless steel throughout for superior corrosion resistance and lasting appearance. Note that this system will not fit vehicles equipped with the optional bed step. Extension pipes are available separately: use 60734 for Crew Cab with Standard Bed (6'6", 157.7" wheelbase) or 60735 for Extended Cab with Long Bed (6'1", 164.6" wheelbase).

Backed by Borla's Million-Mile Warranty, this exhaust system represents decades of racing expertise and engineering excellence from the world's most trusted performance exhaust manufacturer.
