AVOTurboworld's Gen 3 header back full exhaust for the FB Series XV 2.0i 2012-2017 model offer improved flow and a deep, smooth sound. The full system includes a 5" body cat converter and is 2.5" stainless steel all the way through to rear of the vehicle. It has a resonator in the middle section to a large rear muffler that has quad tapered exhaust tips. AVO have also fitted a stainless OEM style flex as it is required with the replacement of the factory OEM version. Without the donut gasket and OEM spring loaded bolt setup then your headers and any welds forward of the flex are prone to cracking. The stainless flanges are a lost wax stainless casting that are 13mm thick and will not warp under the harshest of conditions. The thickness of our exhaust tube is 1.5mm which is thicker than most aftermarket front pipes. This helps with noise absorption and with longevity of the product.
