This Borla S-Type Cat-Back exhaust system is a 2.5 inch diameter True Dual design built specifically for the INFINITI Q50. It uses a merge X-Pipe and Borla's patented Polyphonic Harmonizer technology, which blends pipes of different diameters and lengths to create a clean, rich, full-bodied sound. The system exits through a single 4.5 inch bright chrome on T-304 stainless steel tip on each tail pipe. The classic S-Type sound level delivers a sportier, refined tone with no drone inside the cabin. Borla Cat-Back and Axle-Back systems use patented straight-through, multi-core technology to free up hidden horsepower, and the added exhaust velocity brings more power, driving excitement, and the distinctive Borla Sound of Power. The system is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and CNC manufacturing for an accurate, long-lasting fit. Like all Borla exhaust, it is handmade in the USA. As a street Cat-Back system that mounts behind the factory catalytic converters, it is 50-state emissions legal. It is backed by the Borla Million-Mile Warranty.
