Description
The Borla ATAK Cat-Back System, part number 140516 (Summit Racing part number BOR-140516; UPC 808422405164), is a rear-exit, dual-in/dual-out exhaust system made from natural-finish 304 stainless steel. It includes a merge X-pipe and Borla’s ATAK acoustical technology, developed to deliver a louder exhaust note while retaining sound clarity across the RPM range.
ATAK—Acoustically Tuned Applied Kinetics—is Borla’s highest-decibel-level technology in its street-legal lineup. The system also uses Borla’s multi-core design, which the manufacturer says is intended to support power gains. CNC-machined components and ultra-smooth mandrel bends are designed to promote flow, accurate fit, performance, and durability.
