Fiesta ST 1.6L 2.5" Mandrel-Bent Cat-Back Exhaust System

The FSWERKS Sport Exhaust system is a direct replacement cat-back system engineered for the Ford Fiesta ST 1.6L (2014-2019). Constructed from heavy-wall T304 stainless steel, it utilizes 2.5" mandrel-bent tubing to maximize exhaust flow and potential horsepower gains. The system is TIG and MIG welded, with laser-cut T304 stainless steel flanges and solid bar hanger rods for durability. This exhaust system features a high-flow, straight-through muffler design and is finished with aggressive-looking, polished dual 3" angle cut T304 stainless steel tips, etched with FSWERKS logos. It retains all emissions equipment, making it 50-state street legal. The FSWERKS system is approximately 5 lbs lighter than the stock OEM exhaust. Installation is facilitated by included clamps, hardware, and instructions. The system is backed by a 5-year limited warranty. Users report easy installation, a deep tone without drone, and noticeable performance improvements. Peak gains are cited as +5.4 whp & +4.3 wtq, with max gains reaching +11.5 whp @ 6,200rpm & +10 wtq @ 2,800rpm.
