Borla Performance Exhaust 12-Inch Extension Pipe - 2019-2026 Silverado/Sierra 1500 2.7L/4.3L/5.3L (60708)
Adapt your aftermarket cat-back system to accommodate longer truck bed configurations with the Borla Performance Exhaust 12-Inch Extension Pipe for 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 light-duty pickups. This specialized mid-pipe adapter is specifically engineered to convert a Borla exhaust kit built for a 147.4-inch wheelbase into a flawless fit for a 157-inch wheelbase chassis. This layout corresponds to the popular Crew Cab configuration fitted with a 6-foot-7-inch Standard Bed. Designed for trucks powered by the 2.7L Turbo 4-cylinder, 4.3L EcoTec3 V6, or 5.3L EcoTec3 V8 engines, this 3-inch diameter extension inserts smoothly into your exhaust infrastructure to ensure accurate tailpipe placement and hanger alignment without requiring custom cutting or fabrication at an exhaust shop.
Constructed to survive harsh job sites, heavy trailering duties, and winter road salt, this adapter pipe is manufactured from top-tier T-304 austenitic stainless steel to deliver superior resistance against structural rust, oxidation, and splitting. The pipe is precision-formed with a 3-inch inner diameter (I.D.) inlet and a 3-inch outer diameter (O.D.) outlet, spanning an overall length of exactly 12 inches for a clean, leak-free slip-joint connection. High-tech computer numerical control (CNC) manufacturing processes ensure exact sizing and a secure underbody fitment that maintains unrestrictive exhaust velocity. This adapter kit includes a heavy-duty 3-inch installation clamp and is backed by Borla's legendary lifetime Million-Mile Warranty.
