Dinan's axleback expands the exits to 83mm per side, increasing the outlet-to-inlet ratio while retaining the factory valve control for quiet low-speed operation. The result is +4 HP and +3 lb-ft of torque, a genuinely deeper exhaust note unexpected from a 2.0L four-cylinder, and dual 4\" (102mm) polished double-walled tips at the rear that make the stock 90mm slash-cuts look undersized. 100% T304 stainless steel, TIG welded, drone abatement engineering, factory bracket fitment.
