Description
Noticeable Horsepower and Torque Increase. The Stainless Works Turbo Chambered Split Rear Exit Cat-Back Exhaust with a Performance Connect makes use of a 3″ diameter mandrel-bent tubing to enhance your 5.3L Sierra’s exhaust flow. This allows your truck to gain extra horsepower and torque, upgrading its performance even further.
Built to Last. The Stainless Works Turbo Chambered Cat-Back Exhaust is constructed from T304 stainless steel, a material that has been made to withstand the toughest of drives. This construction makes the exhaust corrosion-resistant, which gives the piece a longer lifespan.
Sounds Amazing and Powerful. The Stainless Works Turbo Chambered Cat-Back Exhaust lets your 5.3L Sierra give off a strong, aggressive growl. Thanks to the exhaust’s slash-cut, double-wall polished tips and chambered turbo mufflers, no one in the road can ignore your truck’s roar.
Direct Fit Upgrade. Stainless Works designed their Cat-Back to be installed with a pair of their “Performance Connect” Long Tube Headers. There is no cutting or extra modifications required. Installation of this Stainless Works Exhaust can be completed in about a two hours with just basic hand tools.
