Borla S-Type Dual Exhaust System with Polished Tips; Rear Exit (09-13 4.8L Sierra 1500)

Improves Exhaust Sound. Creating an aggressive, competent, energetic exhaust note, the Borla Stinger S-Type Dual Rear Exit Cat-Back Exhaust also adds a welcome boost of +7-10% horsepower and ft/lbs of torque to your 2009-2013 Sierra. Sending the exhaust through a single 2.75” intermediate pipe to the high-flow, multi-core muffler, the Stinger Cat-Back then splits it between two 2.25” tailpipes ending in polished 4” exhaust tips. These tips feature rolled angle-cut tips for extra style and exit straight out the rear of your pickup. The high gas flow through these mandrel-bent pipes also increases fuel economy at cruising speed, letting you get farther on each tank of gasoline.

Borla manufactures the Stinger S-Type Cat-Back Exhaust out of austenitic stainless steel for maximum rust and corrosion resistance, explaining the 1 million mile limited warranty applying to each exhaust system. The part is all-welded, including the pipes and the muffler, to prevent any risk of leaking. The muffler incorporates both stainless steel and ceramic internal elements for high durability. This component is proudly USA-made and is supplied with all the hardware needed for an easy bolt-on installation.
