Cat-Back Chevrolet Silverado 1500 Exhaust System

Increase your horsepower and performance while improving your sound level all with one exhaust system. While the price is slightly higher and the installation a little bit more demanding than the axle-back, it will all be worth it because, with Borla 140540 Cat-Back Exhaust System, you will experience a significant improvement in your performance and torque, and a sound level of around 123.6 DB, which is totally crazy!

Heavy-duty stainless steel construction

Constructed from heavy-duty stainless steel, you can expect the longest usability period from this exhaust system. The steel is tough against damaging elements and is made to resist corrosion and rust for long-lasting durability on your Chevrolet Silverado 1500.

Mandrel-bent tubing

Another bonus to the Chevrolet Silverado 1500 exhaust system's construction is the mandrel-bent tubing, which ensures the pipe maintains its size and shape throughout the length, to allow free-flowing. Mandrel-bent tubes are also known for their durability.

Reduce back pressure and Absorb sound waves

Borla 140540 Cat-Back Exhaust System uses straight-through muffler design which reduces backpressure and absorbs sound waves. This is in contrast to chambered mufflers which use baffles, or partitions to absorb sound waves and this reduces power while also creating backpressure.

Better fuel economy

The exhaust system does not only improve horsepower and sound level, but it also reduces fuel usage whenever you get at cruising speed.


This cat-back system has been specifically engineered for your Chevrolet Silverado 1500 to deliver the most horsepower and desirable sound. Some exhaust systems are designed with universal fitting to work on every vehicle. While this has its advantages, its main disadvantage is that it will not make the most out of your system, and the improvement in horsepower and sound quality will not be very significant.

One-million mile warranty

You will get a one-million mile warranty on every Borla 140540 ATAK Cat-Back Exhaust System you purchase. This is to assure you that the system will work great and in the rare chance of a manufacturing defect, we will always have your back.

Made in the USA

Made right here in the USA, this exhaust system features superior quality materials, combined with cutting-edge technology that keep the system up to standards and ensure its performance meets, or better still, exceed your expectation.
