Borla Performance Exhaust 12-Inch Extension Pipe - 2019-2026 Silverado/Sierra 1500 6.2L V8 (60706)
Adapt your high-performance exhaust system to fit longer-wheelbase configurations with the Borla Performance Exhaust 12-Inch Extension Pipe for 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. This specialized adapter pipe is specifically engineered to stretch a Borla cat-back exhaust system designed for a 147.4-inch wheelbase up to perfectly fit models with a 157-inch wheelbase. This configuration corresponds directly to the spacious Crew Cab layout equipped with a 6-foot-7-inch Standard Bed. By slipping this precision-fit extension into place, truck owners running the heavy-hitting 6.2L V8 engine can achieve exact hangar alignment and flawless under-chassis routing without the need for custom fabrication or makeshift exhaust shop modifications.
Built to handle heavy towing workloads, rugged job sites, and extreme thermal demands, this heavy-gauge adapter pipe is manufactured from premium 3.5-inch diameter T-304 austenitic stainless steel to provide unmatched resistance against structural rust, road salt weathering, and mud corrosion. The pipe features a 3.5-inch inner diameter (I.D.) inlet paired with a 3.5-inch outer diameter (O.D.) outlet spanning exactly 12 inches in length for a tight, leak-free slip-joint connection. Precision computer numerical control (CNC) manufacturing processes ensure accurate end-forming and perfect sizing. This adapter kit comes complete with a heavy-duty exhaust clamp and is backed by Borla's legendary lifetime Million-Mile Warranty.
