Axle-Back Exhaust Systems

Description

This system features the aggressive ATAK(r) sound with no drone inside the vehicle. The 2.75" diameter (1 tail pipe on each side is 2.5") system has dual tips on each muffler assembly and will fit vehicles with Dual Mode Exhaust (NPP) valves but it does NOT include NPP valves. Adapter kit 60605 can be used to add NPP valves this Axle-Back system. It may be used with the dual tip lower bumper cover to convert a single, split rear exit to a dual split rear exit. By adding Borla(r) X-Pipe with Mid-Pipes part number 60607 (WITHOUT AFM Valves), or 60610 (With AFM Valves) you can create a Cat-Back(tm) system for your Camaro SS Coupe. The X-Pipes with Mid-Pipes do NOT fit Convertibles. It features dual 4" round polished T-304 stainless steel tips on each muffler assembly. Systems with black coated T-304 stainless steel tips, and carbon fiber tips are also available. Borla(r) Cat-Back(tm) & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive Borla(r) Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, Borla(r) stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
