The enlarged bore construction improves exhaust flow without sacrificing mid-range torque.
Construction and Appearance. Crafted from aerospace grade Type 304 non-magnetic stainless steel, this system provides exceptional durability and corrosion resistance.

Each system is engineered and hand-finished in the UK for superior craftsmanship and precise fitment.
Installation. Installation is easy with a direct-fit design utilizing factory mounting points. Drilling is not required; however, a Roush Performance rear valance is required for proper quad-tip fitment.
