Borla ATAK Cat-Back Exhaust System for 2019-2023 Chevrolet Silverado 1500 & GMC Sierra 1500 6.2L (Dual Round Rolled Angle-Cut tips)

The ATAK Cat-Back Exhaust System puts Borla's most aggressive sound level on the exhaust path behind the catalytic converters. ATAK muffler cores are modeled and tuned for this platform so the volume comes with a clean, defined tone. It is Borla part 140776, built for the 2019-2023 Chevrolet Silverado 1500 and GMC Sierra 1500.

Installation is not included, and any extension pipe, tip or other optional Borla part called out in the fit notes is sold separately.

Features

Loudest Borla sound level
ATAK delivers the highest volume in the Borla lineup, above S-Type and Touring, with a full-bodied and aggressive character.

ATAK multi-core muffler technology
ATAK stands for Acoustically-Tuned Applied Kinetics. ATAK mufflers hold several solid and perforated cores, and Borla uses computer modeling to adjust their shapes and perforation patterns until the note is right for the vehicle.

Smooth mandrel-bent tubing throughout
Every bend is mandrel formed, so the tube keeps a full round cross-section instead of crimping, which keeps exhaust flow smooth from front to back.

T-304 stainless steel construction
The system is built from T-304 austenitic stainless steel, which holds up to heat and corrosion better than 409 or aluminized steel.

CNC-built for accurate fitment
Borla uses computer numerical control manufacturing so each piece lines up with the vehicle it was designed for.

Covered by the Million-Mile Warranty
Materials and workmanship are covered for the original buyer on the original vehicle; tip finishes, coatings, carbon fiber and moving parts carry one year.

Warranty, Shipping & Returns

Warranty. Borla covers its products under the Million-Mile Warranty, which protects the original purchaser of record, on the vehicle the part was first installed on, against defects in materials or workmanship for a million miles. Carbon fiber, black coatings, tip finishes and moving parts such as valves and actuators carry a one-year term, and appearance blemishes from weather, road hazards, lack of maintenance or temperature extremes are not covered. When Borla's inspection confirms a defect, Borla repairs or replaces the part at its option. The warranty does not pay for removal or reinstallation, does not apply to parts damaged by accident, abuse, misuse, misapplication or modification, and does not cover sound level, because sound is a matter of taste. Shipping. The carrier and ship method are set by the size and weight of the carton when the order is placed; long exhaust systems ship in oversize cartons. Inspect on delivery. When the carton arrives, open it and check every pipe, muffler, clamp and hanger against the parts list before you start the install, and report any shipping damage right away with photos.

Returns. Unused items in their original packaging can be returned within 30 days of delivery. If an item arrives damaged, defective or wrong, return shipping is on us. See our Returns & Refunds Policy, or email support@prestigetruck.com with any question.
